- 15 (Indicating the other factor in the row/column) How can you use prime factors to find all factors of 15? Prime factors are 3 and 5. The factors are formed by taking all possible products of these prime factors, including the product of no prime factors (which is 1) and each prime factor raised to its powers up to the power in the prime factorization (which is 1 for both 3 and 5). Possible combinations - No prime factors 1 - 3 to the power of 1 3 - 5 to the power of 1 5 - 3 to the power of 1 times 5 to the power of 1 3 x 5 = 15 So the factors are 1, 3, 5, 15. Apply this method to find the factors of other numbers. Example Factors of 12. Prime factorization 2^2 x 3^1. Combinations - 2^0 x 3^0 = 1 - 2^1 x 3^0 = 2 - 2^2 x 3^0 = 4 - 2^0 x 3^1 = 3 - 2^1 x 3^1 = 6 - 2^2 x 3^1 = 12 Factors of 12 1, 2, 3, 4, 6, 12. This confirms the method. Are there any types of numbers where finding factors is particularly easy or difficult? For prime numbers, factors are easy to find (only 1 and themselves). For numbers with many prime factors or high powers of prime factors, finding all factors can be more involved but systematic using prime factorization. Perfect squares have an odd number of factors. Why? In factor pairs, the factors are usually distinct. For a perfect square, one factor is repeated (the square root), leading to an odd number of unique factors. Example Factors of 9 (3^2) 1, 3, 9 (3 factors). Factor pairs (1, 9), (3, 3). Example Factors of 16 (2^4) 1, 2, 4, 8, 16 (5 factors). Factor pairs (1, 16), (2, 8), (4, 4). 15 is not a perfect square, and it has an even number of factors (4). Can you relate the factors of 15 to divisibility tests? Divisibility by 1 All integers are divisible by 1. 15 is divisible by 1. Divisibility by 3 The sum of the digits of 15 (1+5=6) is divisible by 3, so 15 is divisible by 3. Divisibility by 5 The last digit of 15 is 5, so 15 is divisible by 5. Divisibility by 15 A number is divisible by 15 if it is divisible by both 3 and 5. 15 satisfies this. Consider divisibility by 2, 4, 6, etc., and why 15 does not satisfy those based on its factors. 15 is odd, so not divisible by 2, 4, 6, 8, 10, 12, 14. Sum of digits is not divisible by 9, so not divisible by 9. Last digit is not 0, so not divisible by 10. The pattern of alternating sum of digits is not divisible by 11. The number formed by the last two digits is not divisible by 4. A number divisible by 6 must be divisible by 2 and 3 (15 is divisible by 3 but not 2). These divisibility rules are based on the prime factors and their powers. If you had to teach someone about factors using only visual aids for the number 15, what would you use? Arrays of 15 objects (1x15, 3x5, 5x3, 15x1). Factor rainbow connecting pairs. Groups of 15 divided into equal subgroups (1 group of 15, 3 groups of 5, 5 groups of 3, 15 groups of 1). Number line with jumps of factor sizes landing on 15. Can you write a short story or scenario where the factors of 15 play a key role? "A baker had 15 cookies to arrange on plates. She wanted to put the same number of cookies on each plate and have no cookies left over. The number of plates she could use had to be a factor of 15. What were her options?" (1 plate of 15, 3 plates of 5, 5 plates of 3, 15 plates of 1). Create other scenarios involving sharing, grouping, or arranging 15 items. A gardener has 15 plants to plant in rows with equal numbers in each row. How many possible arrangements are there? A teacher wants to divide 15 students into equal-sized groups. What are the possible group sizes? If the area of a rectangular garden bed is 15 square meters and the sides are whole numbers, what are the possible dimensions? These scenarios help illustrate the practical application of factors. Consider the number of factors of numbers that are one less or one more than 15 (14 and 16). Number of factors of 14 (2 x 7) (1+1) x (1+1) = 4 (1, 2, 7, 14). Number of factors of 16 (2^4) 4 + 1 = 5 (1, 2, 4, 8, 16). The number of factors can vary greatly for nearby numbers. What are the aliquot divisors of 15? (The proper divisors, excluding the number itself) The proper divisors of 15 are 1, 3, 5. The sum of the aliquot divisors is 1 + 3 + 5 = 9. If the sum of the aliquot divisors is less than the number, it is a deficient number (15 > 9, so 15 is deficient). If the sum is equal to the number, it is a perfect number (e.g., 6 1 + 2 + 3 = 6). If the sum is greater than the number, it is an abundant number (e.g., 12 1 + 2 + 3 + 4 + 6 = 16 > 12). Classify 15 based on the sum of its aliquot divisors. Are there any specific theorems related to the factors of a number? Fundamental Theorem of Arithmetic (unique prime factorization). Number of divisors function (τ(n) based on prime factorization). Sum of divisors function (σ(n) based on prime factorization). For 15 = 3^1 x 5^1 τ(15) = (1+1) x (1+1) = 4 (number of factors). σ(15) = ((3^(1+1) - 1) / (3 - 1)) * ((5^(1+1) - 1) / (5 - 1)) = ((9 - 1) / 2) * ((25 - 1) / 4) = (8 / 2) * (24 / 4) = 4 * 6 = 24 (sum of factors). These formulas provide a systematic way to find the number and sum of factors using prime factorization. Can you relate the concept of factors to fractions and ratios? When simplifying fractions, you divide both numerator and denominator by a common factor. Ratios can be simplified by dividing by the greatest common factor. Example Ratio 15 40. GCD(15, 40) = 5. Simplified ratio 3 8. Consider a scenario involving proportions where factors are relevant. If a recipe for 15 cookies requires certain amounts of ingredients, you can use factors to scale the recipe for a different number of cookies (if that number is a factor or multiple of 15). Example Recipe for 15 cookies needs 1 cup of flour. To make 5 cookies (15 / 3), you would need 1/3 cup of flour. This uses the inverse relationship of factors in scaling.
