Least Common Multiple of 12/57,82/42,426/12

Given numbers are 12/57,82/42,426/12

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 12,82,426

Least Common Multiple of Numerators i.e. LCM of 12,82,426 is 34932.

GCF of Denominators means GCF of 57,42,12 as per the given fractions.

GCF of 57,42,12 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 12,82,426

LCM of Fractions 12/57,82/42,426/12 is 11644

2 12, 82, 426
3 6, 41, 213
2, 41, 71

∴ So the LCM of the given numbers is 2 x 3 x 2 x 41 x 71 = 34932

Least Common Multiple of 12,82,426 with GCF Formula

Least Common Multiple of 12,82,426 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 12,82,426 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,82,426) = 2

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

GCF(12,82,426) x common factors =2 x 6 = 12

LCM(12,82,426) = ( 12 × 82 × 426 ) / 12

LCM(12,82,426) = 419184 / 12

LCM(12,82,426) = 34932


Lets's calculate GCF of 57,42,12

3 57, 42, 12
19, 14, 4

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 34932/3

Therefore the LCM of Fractions 12/57,82/42,426/12 is 11644
