LCM of 56/66, 10/21, 60/615

Enter two or more fractions separated by "commas"

Ex: 2/3, 5/7 or 3/5, 5/9, 7/3

LCM of:

Least Common Multiple of 56/66,10/21,60/615

Given numbers are 56/66,10/21,60/615

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 56,10,60

Least Common Multiple of Numerators i.e. LCM of 56,10,60 is 840.

GCF of Denominators means GCF of 66,21,615 as per the given fractions.

GCF of 66,21,615 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 56,10,60

LCM of Fractions 56/66,10/21,60/615 is 280

2 56, 10, 60
2 28, 5, 30
5 14, 5, 15
14, 1, 3

∴ So the LCM of the given numbers is 2 x 2 x 5 x 14 x 1 x 3 = 840

Least Common Multiple of 56,10,60 with GCF Formula

Least Common Multiple of 56,10,60 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 56,10,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,10,60) = 2

common factors(in case of two or more numbers have common factors) = 20

GCF(56,10,60) x common factors =2 x 20 = 40

LCM(56,10,60) = ( 56 × 10 × 60 ) / 40

LCM(56,10,60) = 33600 / 40

LCM(56,10,60) = 840


Lets's calculate GCF of 66,21,615

3 66, 21, 615
22, 7, 205

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 840/3

Therefore the LCM of Fractions 56/66,10/21,60/615 is 280
