1 and 12, 2 and 6, 3 and 4
The factors of 12 are: 1, 2, 3, 4, 6, 12. Those which are not multiples of 3 are: 1, 2, 4.
2 x 6 = 12 2 and 12 are factors of 12 2 and 6 are a factor pair of 12
12 is a multiple of 2.
The factor that does not belong in the sequence is 1. The sequence follows a pattern of multiplying by 2: 2 x 2 = 4, 4 x 2 = 8, 8 x 2 = 16. However, 1 does not fit this pattern and disrupts the sequence.
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
12 is not a factor of any number between 1 and 10. But 1, 2, 3, 4, and 6 are factors of 12 .
