LCM of:

Least Common Multiple of 291/681,160/780

Given numbers are 291/681,160/780

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 291,160

Least Common Multiple of Numerators i.e. LCM of 291,160 is 46560.

GCF of Denominators means GCF of 681,780 as per the given fractions.

GCF of 681,780 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 291,160

LCM of Fractions 291/681,160/780 is 15520

Given numbers has no common factors except 1. So, there LCM is their product i.e 46560

Least Common Multiple of 291,160 with GCF Formula

Least Common Multiple of 291,160 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 291,160 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(291,160) = 1

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

GCF(291,160) x common factors =1 x 1 = 1

LCM(291,160) = ( 291 × 160 ) / 1

LCM(291,160) = 46560 / 1

LCM(291,160) = 46560


Lets's calculate GCF of 681,780

3 681, 780
227, 260

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 46560/3

Therefore the LCM of Fractions 291/681,160/780 is 15520
