LCM of:

Least Common Multiple of 63/891,57/426

Given numbers are 63/891,57/426

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 63,57

Least Common Multiple of Numerators i.e. LCM of 63,57 is 1197.

GCF of Denominators means GCF of 891,426 as per the given fractions.

GCF of 891,426 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 63,57

LCM of Fractions 63/891,57/426 is 399

3 63, 57
21, 19

∴ So the LCM of the given numbers is 3 x 21 x 19 = 1197

Least Common Multiple of 63,57 with GCF Formula

Least Common Multiple of 63,57 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 63,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,57) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(63,57) x common factors =3 x 1 = 3

LCM(63,57) = ( 63 × 57 ) / 3

LCM(63,57) = 3591 / 3

LCM(63,57) = 1197


Lets's calculate GCF of 891,426

3 891, 426
297, 142

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1197/3

Therefore the LCM of Fractions 63/891,57/426 is 399
