LCM of:

Least Common Multiple of 857/18,640/1688

Given numbers are 857/18,640/1688

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 857,640

Least Common Multiple of Numerators i.e. LCM of 857,640 is 548480.

GCF of Denominators means GCF of 18,1688 as per the given fractions.

GCF of 18,1688 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 857,640

LCM of Fractions 857/18,640/1688 is 274240

Given numbers has no common factors except 1. So, there LCM is their product i.e 548480

Least Common Multiple of 857,640 with GCF Formula

Least Common Multiple of 857,640 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 857,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(857,640) = 1

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

GCF(857,640) x common factors =1 x 1 = 1

LCM(857,640) = ( 857 × 640 ) / 1

LCM(857,640) = 548480 / 1

LCM(857,640) = 548480


Lets's calculate GCF of 18,1688

2 18, 1688
9, 844

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 548480/2

Therefore the LCM of Fractions 857/18,640/1688 is 274240
