Least Common Multiple of 80/71,98/73,42/75,42/197

Given numbers are 80/71,98/73,42/75,42/197

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 80,98,42,42

Least Common Multiple of Numerators i.e. LCM of 80,98,42,42 is 11760.

GCF of Denominators means GCF of 71,73,75,197 as per the given fractions.

GCF of 71,73,75,197 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 80,98,42,42

LCM of Fractions 80/71,98/73,42/75,42/197 is 11760

2 80, 98, 42, 42
3 40, 49, 21, 21
7 40, 49, 7, 7
40, 1, 1, 7

∴ So the LCM of the given numbers is 2 x 3 x 7 x 40 x 1 x 1 x 7 = 11760

Least Common Multiple of 80,98,42,42 with GCF Formula

Least Common Multiple of 80,98,42,42 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 80,98,42,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,98,42,42) = 2

common factors(in case of two or more numbers have common factors) = 588

GCF(80,98,42,42) x common factors =2 x 588 = 1176

LCM(80,98,42,42) = ( 80 × 98 × 42 × 42 ) / 1176

LCM(80,98,42,42) = 13829760 / 1176

LCM(80,98,42,42) = 11760


Lets's calculate GCF of 71,73,75,197

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11760/1

Therefore the LCM of Fractions 80/71,98/73,42/75,42/197 is 11760
