LCM of:

Least Common Multiple of 681/56,611/640

Given numbers are 681/56,611/640

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 681,611

Least Common Multiple of Numerators i.e. LCM of 681,611 is 416091.

GCF of Denominators means GCF of 56,640 as per the given fractions.

GCF of 56,640 is 8 as it is the largest common factor for these numbers.

Lets's calculate LCM of 681,611

LCM of Fractions 681/56,611/640 is 416091/8

Given numbers has no common factors except 1. So, there LCM is their product i.e 416091

Least Common Multiple of 681,611 with GCF Formula

Least Common Multiple of 681,611 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 681,611 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(681,611) = 1

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

GCF(681,611) x common factors =1 x 1 = 1

LCM(681,611) = ( 681 × 611 ) / 1

LCM(681,611) = 416091 / 1

LCM(681,611) = 416091


Lets's calculate GCF of 56,640

2 56, 640
2 28, 320
2 14, 160
7, 80

∴ So the GCF of the given numbers is 2 x 2 x 2 = 8

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 416091/8

Therefore the LCM of Fractions 681/56,611/640 is 416091/8
