What is the GCF of 8.

Question

I need help i am only in the 6 drade and i dont know what it is 

Answer 1

GCF stands for greatest common factor.  A factor of a number, is a number multiplied by another to get the desired number.  For example, 4 x 2 = 8.  Both 4 and 2 are factors of 8.  GCF means you are looking for the largest number that is a factor of two different numbers.  You can't have a GCF unless you have two different numbers.  For example, the GCF of 8 and 16 would be 8.  1 x 8 = 8     2 x 8 = 16          8 is the largest number that can be multiplied to get both numbers.
