Since 12 is a factor of 72, all of its factors are common.
The common factors are: 1, 2, 3, 4, 6, 12. 12 is the greatest common factor of 72 and 84. All the factors of 12 will therefore divide by both 72 and 84.
The common factors are: 1, 2, 3, 4, 6, 12
The common factors of 24 and 72 are: 1, 2, 3, 4, 6, 8, 12, and 24The common factors are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 72 are 1,2,3,4,6,8,9,12,18,24,36,72.
The common factors are: 1, 2, 3, 4, 6, 8, 12, 24
1,2,3,4,6,12
Since 12 is a factor of 72, it is automatically the GCF.
There are no common factors of 72 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The prime factors of 72 are 2, 2, 2, 3, and 3.
Since 12 is a factor of 72, all of its factors are common.
The GCF is 12.
