Least Common Multiple of 40/40,81/80,26/51,72/355

Given numbers are 40/40,81/80,26/51,72/355

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 40,81,26,72

Least Common Multiple of Numerators i.e. LCM of 40,81,26,72 is 42120.

GCF of Denominators means GCF of 40,80,51,355 as per the given fractions.

GCF of 40,80,51,355 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 40,81,26,72

LCM of Fractions 40/40,81/80,26/51,72/355 is 42120

2 40, 81, 26, 72
2 20, 81, 13, 36
2 10, 81, 13, 18
3 5, 81, 13, 9
3 5, 27, 13, 3
5, 9, 13, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 5 x 9 x 13 x 1 = 42120

Least Common Multiple of 40,81,26,72 with GCF Formula

Least Common Multiple of 40,81,26,72 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 40,81,26,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,81,26,72) = 1

common factors(in case of two or more numbers have common factors) = 144

GCF(40,81,26,72) x common factors =1 x 144 = 144

LCM(40,81,26,72) = ( 40 × 81 × 26 × 72 ) / 144

LCM(40,81,26,72) = 6065280 / 144

LCM(40,81,26,72) = 42120


Lets's calculate GCF of 40,80,51,355

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 42120/1

Therefore the LCM of Fractions 40/40,81/80,26/51,72/355 is 42120
