The factors of 12 are:
1, 2, 3, 4, 6, 12
The factors of 72 are:
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The factors of 75 are:
1, 3, 5, 15, 25, 75
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72Factors of 75: 1, 3, 5, 15, 25, 75GCF (72, 75) = 3
7 + 5 = 12 12 x 6 = 72 72 + 3 = 75 3 + [6 x (5 + 7)] = 75 3 + [6 x 12] = 3 + 72 = 75

No. 72 has 12 factors.
Six goes into 75 a total of 12 times with a remainder. Specifically, when you divide 75 by 6, you get 12 with a remainder of 3, since ( 6 \times 12 = 72 ) and ( 75 - 72 = 3 ).
The gcf is 3
72 has 12 factors: 1 2 3 4 6 8 9 12 18 24 36 72.
6 multiplied by 12 is 72.
12 with 3 remaining 75 - 3 = 72 = 6 x 12
Yes.
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.
