LCM of:

Least Common Multiple of 42/991,78/536,349/460

Given numbers are 42/991,78/536,349/460

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 42,78,349

Least Common Multiple of Numerators i.e. LCM of 42,78,349 is 190554.

GCF of Denominators means GCF of 991,536,460 as per the given fractions.

GCF of 991,536,460 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,78,349

LCM of Fractions 42/991,78/536,349/460 is 190554

2 42, 78, 349
3 21, 39, 349
7, 13, 349

∴ So the LCM of the given numbers is 2 x 3 x 7 x 13 x 349 = 190554

Least Common Multiple of 42,78,349 with GCF Formula

Least Common Multiple of 42,78,349 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 42,78,349 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,78,349) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(42,78,349) x common factors =1 x 6 = 6

LCM(42,78,349) = ( 42 × 78 × 349 ) / 6

LCM(42,78,349) = 1143324 / 6

LCM(42,78,349) = 190554


Lets's calculate GCF of 991,536,460

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 190554/1

Therefore the LCM of Fractions 42/991,78/536,349/460 is 190554
