The greatest common factor of one and x is one. This is because the only number that can be multiplied to equal one is one and there is only one x. If you were factoring out the two numbers as an equation, it could be written as either 1(x+1) or x+1.
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
