1 and 3
The common factors of 6, 12, and 30 are 1 and 3
The common factors of 12 and 21 are 1 and 3. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. This means that the greatest common factor is 3. The numbers are 1 and 3
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
The factors of 12 are:1, 2, 3, 4, 6, 12The factors of 21 are:1, 3, 7, 21The Greatest Common Factor:GCF = 3

The common factors of 12 and 14 are 1 and 21 and 2
The common factors of 6 and 21 are 1 and 3.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors of 12 and 42 are 1, 2, 3, and 6.1, 2, 3, 4, 6, 121, 2, 3, 6, 7, 14, 21, 42
1 and 3
The factors of 6 are 1, 2, 3, and 6. The factors of 21 are 1, 3, 7, and 21. The common factors of 6 and 21 are 1 and 3, and the GCF is 3.
The factors of 12 are:1, 2, 3, 4, 6, 12The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The common factors are: 1, 2, 3, 4, 6, 12
Yes. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, 3, 6, 7, 14, 21, and 42. One of the common factors is 6.
