2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
6 = 2 x 3 9 = 3 x 3 15 = 3 x 5 GCF = 3
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
Since 3 is a factor of 6, it is automatically the GCF.
The factors of 18 are:1, 2, 3, 6, 9, 18The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor (GCF) is:6
The GCF is 1.
24 = 2*2*2*390 = 2*3*3*5 So GCF = 2*3 = 6.
GCF(20, 8, 6) = 2.
7
The GCF of 12 and 54 is 6. To find the GCF, write the prime factorizations of each number.The prime factorization of 12 is 2*2*3The prime factorization of 54 is 2*3*3*3The factors in common are 2*3 = 6, so that is the GCF.
6 = 2 x 3 9 = 3 x 3 15 = 3 x 5 GCF = 3
The GCF of -6 and -2 is 2.
The GCF of 4 and 6 is 2.
2 x 2 x 2 x 3 x 7 = 1682 x 2 x 3 x 3 x 5 = 1802 x 3 x 3 x 5 x 5 = 450Select the common factors.2 x 3 = 6, the GCF
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
The GCF of 6 and 15 is 3. 6/15 = 2/5
Factor them. 2 x 3 = 6 2 x 2 x 2 x 3 = 24 Select the common factors. 2 x 3 = 6, the GCF.
