Greatest Common Factor

We found the factors 648,144,611 . The biggest common factor number is the GCF number.
So the greatest common factor 648,144,611 is 1.

Lets's calculate LCM of 51,79,15

3 51, 79, 15
17, 79, 5

∴ So the LCM of the given numbers is 3 x 17 x 79 x 5 = 20145

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20145

Therefore, the GCF of Fractions 648/51,144/79,611/15 is 1/20145

Least Common Multiple of 51,79,15 with GCF Formula

Least Common Multiple of 51,79,15 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 51,79,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,79,15) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(51,79,15) x common factors =1 x 3 = 3

LCM(51,79,15) = ( 51 × 79 × 15 ) / 3

LCM(51,79,15) = 60435 / 3

LCM(51,79,15) = 20145
