Greatest Common Factor

We found the factors 10,81,842 . The biggest common factor number is the GCF number.
So the greatest common factor 10,81,842 is 1.

Lets's calculate LCM of 21,59,76

Given numbers has no common factors except 1. So, there LCM is their product i.e 94164

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/94164

Therefore, the GCF of Fractions 10/21,81/59,842/76 is 1/94164

Least Common Multiple of 21,59,76 with GCF Formula

Least Common Multiple of 21,59,76 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 21,59,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,59,76) = 1

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

GCF(21,59,76) x common factors =1 x 1 = 1

LCM(21,59,76) = ( 21 × 59 × 76 ) / 1

LCM(21,59,76) = 94164 / 1

LCM(21,59,76) = 94164
