The greatest common factor of 8 and 12 is 4.
8
The GCF is 2.
No. A number cannot be a multiple of a number greater than it. 18 is greater than 8 so 8 cannot be a multiple of 18. Nor is 8 a factor of 18. The factors of a number are those numbers which divide into it without remainder.
The greatest common factor (GCF) of 12 and 8 is 4
Everything except 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72.
A factor = a number which can be divided into the given number with no remainder so yes, 12 is a factor of 48 (as is 2, 3, 4, 6, 8, 12, 16, 24 and 48)
Any number can be a factor. It is not a rule that a number has to be a prime number to be a factor. Therefore 6 can be taken as a factor for many numbers for example 24 and 36 both have 6 as a factor.
Anything that's not on this list: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The least common factor of any set of positive integers is 1.
