1, 2, 3, 6, 9, 18
The GCF of 18 and 30 is 6
The GCF is 3.
3 x 6 = 18, 5 x 6 = 30; six is the largest common factor.
10 is the largest common factor
Factor 18 and y then look for the largest common factor form both sets of factors. For example, the factors of 18 are 2,3,6,9,18 if y = 30, then its factors are 2,3,5,6,10,15,30 So the greatest common factor is 6
Since 30 is a factor of 60, and the largest possible factor of 30 is 30, the greatest common factor is 30.
The Greatest Common Factor of 18, 24, 30: 6
The Greatest Common Factor of 18, 27, and 30 is 3.
