Least Common Multiple of 655/21,642/38,851/630

Given numbers are 655/21,642/38,851/630

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 655,642,851

Least Common Multiple of Numerators i.e. LCM of 655,642,851 is 357854010.

GCF of Denominators means GCF of 21,38,630 as per the given fractions.

GCF of 21,38,630 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 655,642,851

LCM of Fractions 655/21,642/38,851/630 is 357854010

Given numbers has no common factors except 1. So, there LCM is their product i.e 357854010

Least Common Multiple of 655,642,851 with GCF Formula

Least Common Multiple of 655,642,851 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 655,642,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(655,642,851) = 1

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

GCF(655,642,851) x common factors =1 x 1 = 1

LCM(655,642,851) = ( 655 × 642 × 851 ) / 1

LCM(655,642,851) = 357854010 / 1

LCM(655,642,851) = 357854010


Lets's calculate GCF of 21,38,630

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 357854010/1

Therefore the LCM of Fractions 655/21,642/38,851/630 is 357854010
