Lets's calculate LCM of 79,209,680

Given numbers has no common factors except 1. So, there LCM is their product i.e 11227480

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/11227480

Therefore, the GCF of Fractions 64/79,42/209,780/680 is 2/11227480

Least Common Multiple of 79,209,680 with GCF Formula

Least Common Multiple of 79,209,680 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 79,209,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(79,209,680) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(79,209,680) x common factors =1 x 1 = 1

LCM(79,209,680) = ( 79 × 209 × 680 ) / 1

LCM(79,209,680) = 11227480 / 1

LCM(79,209,680) = 11227480
