Least Common Multiple of 8/50,7/72,30/22,56/20

Given numbers are 8/50,7/72,30/22,56/20

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 8,7,30,56

Least Common Multiple of Numerators i.e. LCM of 8,7,30,56 is 840.

GCF of Denominators means GCF of 50,72,22,20 as per the given fractions.

GCF of 50,72,22,20 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 8,7,30,56

LCM of Fractions 8/50,7/72,30/22,56/20 is 420

2 8, 7, 30, 56
2 4, 7, 15, 28
2 2, 7, 15, 14
7 1, 7, 15, 7
1, 1, 15, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 1 x 1 x 15 x 1 = 840

Least Common Multiple of 8,7,30,56 with GCF Formula

Least Common Multiple of 8,7,30,56 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 8,7,30,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(8,7,30,56) = 1

common factors(in case of two or more numbers have common factors) = 112

GCF(8,7,30,56) x common factors =1 x 112 = 112

LCM(8,7,30,56) = ( 8 × 7 × 30 × 56 ) / 112

LCM(8,7,30,56) = 94080 / 112

LCM(8,7,30,56) = 840


Lets's calculate GCF of 50,72,22,20

2 50, 72, 22, 20
25, 36, 11, 10

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 840/2

Therefore the LCM of Fractions 8/50,7/72,30/22,56/20 is 420
