Least Common Multiple of 82/84,64/42,74/61,21/735

Given numbers are 82/84,64/42,74/61,21/735

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 82,64,74,21

Least Common Multiple of Numerators i.e. LCM of 82,64,74,21 is 2038848.

GCF of Denominators means GCF of 84,42,61,735 as per the given fractions.

GCF of 84,42,61,735 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 82,64,74,21

LCM of Fractions 82/84,64/42,74/61,21/735 is 2038848

2 82, 64, 74, 21
41, 32, 37, 21

∴ So the LCM of the given numbers is 2 x 41 x 32 x 37 x 21 = 2038848

Least Common Multiple of 82,64,74,21 with GCF Formula

Least Common Multiple of 82,64,74,21 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 82,64,74,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(82,64,74,21) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(82,64,74,21) x common factors =1 x 4 = 4

LCM(82,64,74,21) = ( 82 × 64 × 74 × 21 ) / 4

LCM(82,64,74,21) = 8155392 / 4

LCM(82,64,74,21) = 2038848


Lets's calculate GCF of 84,42,61,735

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2038848/1

Therefore the LCM of Fractions 82/84,64/42,74/61,21/735 is 2038848
