1, 2 1, 2, 3, 4, 6, 12
1 and 12, 2 and 6, 3 and 4
2 x 6 = 12 2 and 12 are factors of 12 2 and 6 are a factor pair of 12
The factors of 12 are: 1, 2, 3, 4, 6, 12. Those which are not multiples of 3 are: 1, 2, 4.
12 is a multiple of 2.
You could make a case for any of them but if those are the factors of 16, 12 does not belong.
4 is not a factor of 18 and is a factor of both 8 and 12
1 and 3
1, 2 1, 2, 3, 4, 6, 12
The least common factor of any pair of numbers, including 10 and 12, is 1. The factors of 10 are 1, 2, 5, and 10. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors of 10 and 12 are 1 and 2. Therefore, the least common factor (the smallest common factor) is 1.
Since 12 is a factor of 72, all of its factors are common.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 16 are 1, 2, 4, 8, and 16. The common factors of 12 and 16 are 1, 2, and 4. Therefore, the least common factor (the smallest common factor) is 1.
Everything except 1, 2, 61 and 122
1, 2, 3, 4, 6, 12
12 is not a factor of any number between 1 and 10. But 1, 2, 3, 4, and 6 are factors of 12 .
