Least Common Multiple of 31/35,70/72,60/35,70/117

Given numbers are 31/35,70/72,60/35,70/117

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 31,70,60,70

Least Common Multiple of Numerators i.e. LCM of 31,70,60,70 is 13020.

GCF of Denominators means GCF of 35,72,35,117 as per the given fractions.

GCF of 35,72,35,117 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 31,70,60,70

LCM of Fractions 31/35,70/72,60/35,70/117 is 13020

2 31, 70, 60, 70
5 31, 35, 30, 35
7 31, 7, 6, 7
31, 1, 6, 1

∴ So the LCM of the given numbers is 2 x 5 x 7 x 31 x 1 x 6 x 1 = 13020

Least Common Multiple of 31,70,60,70 with GCF Formula

Least Common Multiple of 31,70,60,70 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 31,70,60,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,70,60,70) = 1

common factors(in case of two or more numbers have common factors) = 700

GCF(31,70,60,70) x common factors =1 x 700 = 700

LCM(31,70,60,70) = ( 31 × 70 × 60 × 70 ) / 700

LCM(31,70,60,70) = 9114000 / 700

LCM(31,70,60,70) = 13020


Lets's calculate GCF of 35,72,35,117

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13020/1

Therefore the LCM of Fractions 31/35,70/72,60/35,70/117 is 13020
