Least Common Multiple of 77/72,461/42,242/336

Given numbers are 77/72,461/42,242/336

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 77,461,242

Least Common Multiple of Numerators i.e. LCM of 77,461,242 is 780934.

GCF of Denominators means GCF of 72,42,336 as per the given fractions.

GCF of 72,42,336 is 6 as it is the largest common factor for these numbers.

Lets's calculate LCM of 77,461,242

LCM of Fractions 77/72,461/42,242/336 is 780934/6

11 77, 461, 242
7, 461, 22

∴ So the LCM of the given numbers is 11 x 7 x 461 x 22 = 780934

Least Common Multiple of 77,461,242 with GCF Formula

Least Common Multiple of 77,461,242 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 77,461,242 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,461,242) = 1

common factors(in case of two or more numbers have common factors) = 11

GCF(77,461,242) x common factors =1 x 11 = 11

LCM(77,461,242) = ( 77 × 461 × 242 ) / 11

LCM(77,461,242) = 8590274 / 11

LCM(77,461,242) = 780934


Lets's calculate GCF of 72,42,336

2 72, 42, 336
3 36, 21, 168
12, 7, 56

∴ So the GCF of the given numbers is 2 x 3 = 6

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 780934/6

Therefore the LCM of Fractions 77/72,461/42,242/336 is 780934/6
