3 and all of its multiples.
1 and 3
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.
1, 2, 3 & 6
3 and 5 are both prime numbers and 1 is their only common factor.
common factors of both numbers are: 1 and 3
Common factors of both numbers are: 1, 2, 3 and 6
The common factors are: 1, 5
The numbers that go into both 3 and 8 are their common factors. For 3, the factors are 1 and 3, while for 8, the factors are 1, 2, 4, and 8. The only common factor between them is 1. Thus, 1 is the only number that goes into both 3 and 8.
The factors of 7 are 1 and 7. The factors of 21 are 1, 3, 7, and 21. The only numbers that are factors of BOTH 7 and 21 are 1 and 7.
The factors of 10 are: 1, 2, 5, 10The factors of 15 are:1, 3, 5, 15The common factors are: 1, 5
The numbers that go into both 24 and 30 are called common factors. To find the common factors of two numbers, you need to determine all the factors of each number and then identify the numbers that are present in both lists. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24, while the factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The common factors of 24 and 30 are 1, 2, 3, and 6.
Factors of 15: 1, 3, 5, and 15.Factors of 6: 1, 2, 3, and 6.Common factors (numbers on both lists): 1 and 3.Greatest common factor: 3 .
