15 and 5 both go into every multiple of 15 .
5
The lowest number that both 15 and 25 go into is 75. 15 goes into 75 5 times, and 25 goes into 75 three times.
Both 15 and 20 can go into 60, as they are both factors of that number.
The numbers that go into both 12 and 15 are their common factors. The factors of 12 are 1, 2, 3, 4, 6, and 12, while the factors of 15 are 1, 3, 5, and 15. The common factors between the two sets are 1 and 3. Therefore, the numbers that go into both 12 and 15 are 1 and 3.
They both go into 90.
15 and 20 would both go into 60. Or 300. And several others.
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.
5
The only number that can go into both numbers is 5
