The factors of 10 are: 1, 2, 5, 10
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 2.
2.) The factors of 14 are: 1, 2, 7, 14
The factors of 21 are: 1, 3, 7, 21
Then the greatest common factor is 7.
3.) The factors of 5 are: 1, 5
The factors of 7 are: 1, 7
The factors of 12 are: 1, 2, 3, 4, 6, 12
Then the greatest common factor is 1.
4.) The factors of 4 are: 1, 2, 4
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 20 are: 1, 2, 4, 5, 10, 20
