Least Common Multiple of 24/71,19/81,74/29,76/840

Given numbers are 24/71,19/81,74/29,76/840

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 24,19,74,76

Least Common Multiple of Numerators i.e. LCM of 24,19,74,76 is 16872.

GCF of Denominators means GCF of 71,81,29,840 as per the given fractions.

GCF of 71,81,29,840 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 24,19,74,76

LCM of Fractions 24/71,19/81,74/29,76/840 is 16872

2 24, 19, 74, 76
2 12, 19, 37, 38
19 6, 19, 37, 19
6, 1, 37, 1

∴ So the LCM of the given numbers is 2 x 2 x 19 x 6 x 1 x 37 x 1 = 16872

Least Common Multiple of 24,19,74,76 with GCF Formula

Least Common Multiple of 24,19,74,76 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 24,19,74,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(24,19,74,76) = 1

common factors(in case of two or more numbers have common factors) = 152

GCF(24,19,74,76) x common factors =1 x 152 = 152

LCM(24,19,74,76) = ( 24 × 19 × 74 × 76 ) / 152

LCM(24,19,74,76) = 2564544 / 152

LCM(24,19,74,76) = 16872


Lets's calculate GCF of 71,81,29,840

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16872/1

Therefore the LCM of Fractions 24/71,19/81,74/29,76/840 is 16872
