LCM of:

Least Common Multiple of 531/78,149/3989

Given numbers are 531/78,149/3989

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 531,149

Least Common Multiple of Numerators i.e. LCM of 531,149 is 79119.

GCF of Denominators means GCF of 78,3989 as per the given fractions.

GCF of 78,3989 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 531,149

LCM of Fractions 531/78,149/3989 is 79119

Given numbers has no common factors except 1. So, there LCM is their product i.e 79119

Least Common Multiple of 531,149 with GCF Formula

Least Common Multiple of 531,149 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 531,149 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(531,149) = 1

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

GCF(531,149) x common factors =1 x 1 = 1

LCM(531,149) = ( 531 × 149 ) / 1

LCM(531,149) = 79119 / 1

LCM(531,149) = 79119


Lets's calculate GCF of 78,3989

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79119/1

Therefore the LCM of Fractions 531/78,149/3989 is 79119
