Least Common Multiple of 60/28,18/47,991/711

Given numbers are 60/28,18/47,991/711

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 60,18,991

Least Common Multiple of Numerators i.e. LCM of 60,18,991 is 178380.

GCF of Denominators means GCF of 28,47,711 as per the given fractions.

GCF of 28,47,711 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 60,18,991

LCM of Fractions 60/28,18/47,991/711 is 178380

2 60, 18, 991
3 30, 9, 991
10, 3, 991

∴ So the LCM of the given numbers is 2 x 3 x 10 x 3 x 991 = 178380

Least Common Multiple of 60,18,991 with GCF Formula

Least Common Multiple of 60,18,991 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 60,18,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(60,18,991) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(60,18,991) x common factors =1 x 6 = 6

LCM(60,18,991) = ( 60 × 18 × 991 ) / 6

LCM(60,18,991) = 1070280 / 6

LCM(60,18,991) = 178380


Lets's calculate GCF of 28,47,711

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 178380/1

Therefore the LCM of Fractions 60/28,18/47,991/711 is 178380
