There are 4 positive and 4 negative numbers that go into 15.
They are: 1,3,5,15,-1,-3,-5, and -15.
The numbers that go into both 15 and 70 are their common divisors. The divisors of 15 are 1, 3, 5, and 15, while the divisors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The only common divisors between the two sets are 1 and 5. Therefore, the numbers that go into both 15 and 70 are 1 and 5.
The only number that can go into both numbers is 5
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.
5
3 will go into both of these numbers
1 and 3 go into both.
1 and 7 will go into both the two given numbers
15, 25 and 75
These numbers: 1, 3, 5, 7, 15, 21, 35, 105.
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.
1 and 2.
They have a common factor of 3.1, 2, 3, and 6 go into 6.1, 3, 5, and 15 go into 15.1 and 3 both go into 6 and 15.
