The common factors of 15, 45, and 75 are the numbers that can evenly divide all three of these numbers. To find the common factors, you can first determine the prime factors of each number: 15 = 3 x 5, 45 = 3 x 3 x 5, and 75 = 3 x 5 x 5. The common factors are the numbers that appear in the prime factorization of all three numbers, which in this case are 3 and 5.
The positive integer factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, and 225.1, 3, 5, 9, 15, 25, 45, 75, 225The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225.1, 3, 5, 9, 15, 25, 45, 75, 225
