Least Common Multiple of 680/54,261/28,947/60

Given numbers are 680/54,261/28,947/60

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 680,261,947

Least Common Multiple of Numerators i.e. LCM of 680,261,947 is 168073560.

GCF of Denominators means GCF of 54,28,60 as per the given fractions.

GCF of 54,28,60 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 680,261,947

LCM of Fractions 680/54,261/28,947/60 is 84036780

Given numbers has no common factors except 1. So, there LCM is their product i.e 168073560

Least Common Multiple of 680,261,947 with GCF Formula

Least Common Multiple of 680,261,947 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 680,261,947 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(680,261,947) = 1

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

GCF(680,261,947) x common factors =1 x 1 = 1

LCM(680,261,947) = ( 680 × 261 × 947 ) / 1

LCM(680,261,947) = 168073560 / 1

LCM(680,261,947) = 168073560


Lets's calculate GCF of 54,28,60

2 54, 28, 60
27, 14, 30

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 168073560/2

Therefore the LCM of Fractions 680/54,261/28,947/60 is 84036780
