Lets's calculate LCM of 80,679,387

LCM of Fractions 80/57,679/25,387/389 is 21021840

Given numbers has no common factors except 1. So, there LCM is their product i.e 21021840

Least Common Multiple of 80,679,387 with GCF Formula

Least Common Multiple of 80,679,387 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 80,679,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,679,387) = 1

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

GCF(80,679,387) x common factors =1 x 1 = 1

LCM(80,679,387) = ( 80 × 679 × 387 ) / 1

LCM(80,679,387) = 21021840 / 1

LCM(80,679,387) = 21021840


Lets's calculate GCF of 57,25,389

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21021840/1

Therefore the LCM of Fractions 80/57,679/25,387/389 is 21021840
