The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 64 are: 1, 2, 4, 8, 16, 32, 64 The common factors are: 1, 2 The Greatest Common Factor: GCF = 2
6 is the greatest common factor. 1 is always the least common factor, I am pretty sure you mean the GCF, not the LCF. Look at factors of 18. 18 itself is not a factor of 24, neither is 9 the next factor, but 6 is a factor of both. Nobody really cares about Least common factors, since it is always the same. There is least common multiple? In case you want the LCM, the least common multiple of two numbers is the product divided by the GCF, so is 18 * 24 / 6 = 72
The least common factor of any set of positive integers is 1.
The factors of 18 are: 1, 2, 3, 6, 9, 18The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24The common factors are: 1, 2, 3, 6The Greatest Common Factor (GCF) is:6
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.
