LCM of:

Least Common Multiple of 641/158,1998/500

Given numbers are 641/158,1998/500

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 641,1998

Least Common Multiple of Numerators i.e. LCM of 641,1998 is 1280718.

GCF of Denominators means GCF of 158,500 as per the given fractions.

GCF of 158,500 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 641,1998

LCM of Fractions 641/158,1998/500 is 640359

Given numbers has no common factors except 1. So, there LCM is their product i.e 1280718

Least Common Multiple of 641,1998 with GCF Formula

Least Common Multiple of 641,1998 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 641,1998 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(641,1998) = 1

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

GCF(641,1998) x common factors =1 x 1 = 1

LCM(641,1998) = ( 641 × 1998 ) / 1

LCM(641,1998) = 1280718 / 1

LCM(641,1998) = 1280718


Lets's calculate GCF of 158,500

2 158, 500
79, 250

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1280718/2

Therefore the LCM of Fractions 641/158,1998/500 is 640359
