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.
If x=1 (because if x is 2 or more the number is really weird) then the gif is 2097152.
Prime factorization of: 195= 3 x 5 x 13 273= 3 x .....13 x 7 =============== GCF=3 x .....13 GCF=39
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 ', no matter what whole number 'x' is.
The GCF is 1.
3 x 3 x 5 = 45 2 x 2 x 17 = 68 No common prime factors. The GCF is 1.
13 = 1 x 1352 = 1 x 2 x 2 x 13GCF = 13
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
