Least Common Multiple of 36/378,7983/1240

Given numbers are 36/378,7983/1240

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 36,7983

Least Common Multiple of Numerators i.e. LCM of 36,7983 is 31932.

GCF of Denominators means GCF of 378,1240 as per the given fractions.

GCF of 378,1240 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 36,7983

LCM of Fractions 36/378,7983/1240 is 15966

3 36, 7983
3 12, 2661
4, 887

∴ So the LCM of the given numbers is 3 x 3 x 4 x 887 = 31932

Least Common Multiple of 36,7983 with GCF Formula

Least Common Multiple of 36,7983 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 36,7983 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(36,7983) = 9

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

GCF(36,7983) x common factors =9 x 1 = 9

LCM(36,7983) = ( 36 × 7983 ) / 9

LCM(36,7983) = 287388 / 9

LCM(36,7983) = 31932


Lets's calculate GCF of 378,1240

2 378, 1240
189, 620

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 31932/2

Therefore the LCM of Fractions 36/378,7983/1240 is 15966
