Least Common Multiple of 48/63,32/98,51/57,20/981

Given numbers are 48/63,32/98,51/57,20/981

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 48,32,51,20

Least Common Multiple of Numerators i.e. LCM of 48,32,51,20 is 8160.

GCF of Denominators means GCF of 63,98,57,981 as per the given fractions.

GCF of 63,98,57,981 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 48,32,51,20

LCM of Fractions 48/63,32/98,51/57,20/981 is 8160

2 48, 32, 51, 20
2 24, 16, 51, 10
2 12, 8, 51, 5
2 6, 4, 51, 5
3 3, 2, 51, 5
1, 2, 17, 5

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 1 x 2 x 17 x 5 = 8160

Least Common Multiple of 48,32,51,20 with GCF Formula

Least Common Multiple of 48,32,51,20 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 48,32,51,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(48,32,51,20) = 1

common factors(in case of two or more numbers have common factors) = 192

GCF(48,32,51,20) x common factors =1 x 192 = 192

LCM(48,32,51,20) = ( 48 × 32 × 51 × 20 ) / 192

LCM(48,32,51,20) = 1566720 / 192

LCM(48,32,51,20) = 8160


Lets's calculate GCF of 63,98,57,981

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8160/1

Therefore the LCM of Fractions 48/63,32/98,51/57,20/981 is 8160
