Least Common Multiple of 98/28,57/90,29/400

Given numbers are 98/28,57/90,29/400

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 98,57,29

Least Common Multiple of Numerators i.e. LCM of 98,57,29 is 161994.

GCF of Denominators means GCF of 28,90,400 as per the given fractions.

GCF of 28,90,400 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 98,57,29

LCM of Fractions 98/28,57/90,29/400 is 80997

Given numbers has no common factors except 1. So, there LCM is their product i.e 161994

Least Common Multiple of 98,57,29 with GCF Formula

Least Common Multiple of 98,57,29 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 98,57,29 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(98,57,29) = 1

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

GCF(98,57,29) x common factors =1 x 1 = 1

LCM(98,57,29) = ( 98 × 57 × 29 ) / 1

LCM(98,57,29) = 161994 / 1

LCM(98,57,29) = 161994


Lets's calculate GCF of 28,90,400

2 28, 90, 400
14, 45, 200

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 161994/2

Therefore the LCM of Fractions 98/28,57/90,29/400 is 80997
