LCM of:

Least Common Multiple of 639/42,836/2196

Given numbers are 639/42,836/2196

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 639,836

Least Common Multiple of Numerators i.e. LCM of 639,836 is 534204.

GCF of Denominators means GCF of 42,2196 as per the given fractions.

GCF of 42,2196 is 6 as it is the largest common factor for these numbers.

Lets's calculate LCM of 639,836

LCM of Fractions 639/42,836/2196 is 89034

Given numbers has no common factors except 1. So, there LCM is their product i.e 534204

Least Common Multiple of 639,836 with GCF Formula

Least Common Multiple of 639,836 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 639,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(639,836) = 1

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

GCF(639,836) x common factors =1 x 1 = 1

LCM(639,836) = ( 639 × 836 ) / 1

LCM(639,836) = 534204 / 1

LCM(639,836) = 534204


Lets's calculate GCF of 42,2196

2 42, 2196
3 21, 1098
7, 366

∴ So the GCF of the given numbers is 2 x 3 = 6

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 534204/6

Therefore the LCM of Fractions 639/42,836/2196 is 89034
