That's an infinite list. Numbers with three factors are the squares of prime numbers.
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.
15 and 30 are factors of 60. The factors of 60 include the factors of 15 and 30. 45 is not a factor of 60.
They are the first three odd prime numbers.
3 and 5 both go into multiples of 15, as both numbers are factors of 15. In mathematical terms, 15 is a multiple of both 3 and 5 because it can be evenly divided by both numbers without leaving a remainder.

That's an infinite list. Numbers with three factors are the squares of prime numbers.
The factors of 10 are: 1, 2, 5, 10The factors of 15 are:1, 3, 5, 15The common factors are: 1, 5
The factors of 15 are 1, 3, 5, and 15 .The factors of 75 are 1, 3, 5, 15, 25, and 75 .The common factors ... numbers that are factorsof both 15 and 75 ... are 1, 3, 5, and 15 .
7 and 15 have the number 1 in common as they are both odd numbers. Additionally, they are both integers and prime numbers.
15 Factors of 15: 1, 3, 5, 15 15 = 1 x 15 15 = 3 x 5
No, they are factors of 15. Factors go into numbers, numbers go into multiples.

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 idea is to look for common factors, between the 15 and the 100. Then, divide both numbers by this common factor.
