Lets's calculate LCM of 79,23,21,923

Given numbers has no common factors except 1. So, there LCM is their product i.e 35218911

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/35218911

Therefore, the GCF of Fractions 80/79,66/23,23/21,78/923 is 1/35218911

Least Common Multiple of 79,23,21,923 with GCF Formula

Least Common Multiple of 79,23,21,923 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 79,23,21,923 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(79,23,21,923) = 1

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

GCF(79,23,21,923) x common factors =1 x 1 = 1

LCM(79,23,21,923) = ( 79 × 23 × 21 × 923 ) / 1

LCM(79,23,21,923) = 35218911 / 1

LCM(79,23,21,923) = 35218911
