Least Common Multiple of 161/620,9990/389

Given numbers are 161/620,9990/389

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 161,9990

Least Common Multiple of Numerators i.e. LCM of 161,9990 is 1608390.

GCF of Denominators means GCF of 620,389 as per the given fractions.

GCF of 620,389 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 161,9990

LCM of Fractions 161/620,9990/389 is 1608390

Given numbers has no common factors except 1. So, there LCM is their product i.e 1608390

Least Common Multiple of 161,9990 with GCF Formula

Least Common Multiple of 161,9990 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 161,9990 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(161,9990) = 1

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

GCF(161,9990) x common factors =1 x 1 = 1

LCM(161,9990) = ( 161 × 9990 ) / 1

LCM(161,9990) = 1608390 / 1

LCM(161,9990) = 1608390


Lets's calculate GCF of 620,389

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1608390/1

Therefore the LCM of Fractions 161/620,9990/389 is 1608390
