Least Common Multiple of 18/42,663/49,157/124

Given numbers are 18/42,663/49,157/124

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 18,663,157

Least Common Multiple of Numerators i.e. LCM of 18,663,157 is 624546.

GCF of Denominators means GCF of 42,49,124 as per the given fractions.

GCF of 42,49,124 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 18,663,157

LCM of Fractions 18/42,663/49,157/124 is 624546

3 18, 663, 157
6, 221, 157

∴ So the LCM of the given numbers is 3 x 6 x 221 x 157 = 624546

Least Common Multiple of 18,663,157 with GCF Formula

Least Common Multiple of 18,663,157 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 18,663,157 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,663,157) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(18,663,157) x common factors =1 x 3 = 3

LCM(18,663,157) = ( 18 × 663 × 157 ) / 3

LCM(18,663,157) = 1873638 / 3

LCM(18,663,157) = 624546


Lets's calculate GCF of 42,49,124

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 624546/1

Therefore the LCM of Fractions 18/42,663/49,157/124 is 624546
