If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
Factor them. a x a x b b x b x c a x c x c No common factors. The GCF is 1.
The factors of 21 are 1 x 3 x 7 x 21.The factors of 28 are 1 x 2 x 4 x 7 x 14 x 28.The GCF of 21 and 28 is 7.
Prime factorization of: 195= 3 x 5 x 13 273= 3 x .....13 x 7 =============== GCF=3 x .....13 GCF=39
GCF of 28 42 and 56 is 14.The GCF is 14.(28 = 2 x 14, 42 = 3 x 14, 56 = 4 x 14)To find the GCF, factor the numbers and multiply their common prime factors:28 = 2 x 2 x 742 = 2 x 3 x 756 = 2 x 2 x 2 x 7Common factors are 2 x 7 = 14
If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
3 = 1 x 3 5 = 1 x 5 7 = 1 x 7 GCF = 1
21 = 1 x 3 x 7 30 = 1 x 2 x 3 x 5 44 = 1 x 22 x 11 GCF = 1
The GCF is 1.
The gcf is ' 1 ', no matter what whole number 'x' is.
13 = 1 x 1352 = 1 x 2 x 2 x 13GCF = 13
3 x 3 x 5 = 45 2 x 2 x 17 = 68 No common prime factors. The GCF is 1.
1, 2, 4, 7, 8, 14, 28, 56 1, 3, 9, 27, 81 The GCF is 1.
GCF = 1.89 is prime so its factors are 1 & 8944 = 1 x 2 x 2 x 1135 = 1 x 5 x 7The only factor they have in common is 1.
The GCF is 2^3 x 5.
5 = 1 x 5 99 = 1 x 3 x 3 x 11 GCF = 1
The factors of 59 are: 1, 59 The factors of 81 are: 1, 3, 9, 27, 81
