The GCF is 3.
The GCF is 3.
Factor them. 3 x 5 = 15 2 x 3 x 7 = 42 Select the common factor. The GCF is 3.
15 can be factorized into 3 x 5 42 is factorized as 2 x 3 x 7 Of these factors of these two, greatest common factor is 3. Where as the LCM is found by multiplying the common factor along with non common ones. ie 3 X 2 X 5 X 7 = 210 So HCF or GCF or GCD (Greatest Common Divisor) is 3 Least common multiple is 210
The GCF is: 3
Their GCF is 1. There is no larger common factor.
The GCF is 15.
Yes 6 is the highest common factor of 42 and 48
The greatest common factor of 42 and 66 is 6.6
No, but 7 is a common factor of 42 and 56
Factors of 15: 1, 3, 5, 15. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42. GCF (15, 42) = 3
The greatest common factor of 42 and 12 is 6.
