Least Common Multiple of 21/660,8621/3356

Given numbers are 21/660,8621/3356

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 21,8621

Least Common Multiple of Numerators i.e. LCM of 21,8621 is 181041.

GCF of Denominators means GCF of 660,3356 as per the given fractions.

GCF of 660,3356 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,8621

LCM of Fractions 21/660,8621/3356 is 181041/4

Given numbers has no common factors except 1. So, there LCM is their product i.e 181041

Least Common Multiple of 21,8621 with GCF Formula

Least Common Multiple of 21,8621 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 21,8621 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,8621) = 1

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

GCF(21,8621) x common factors =1 x 1 = 1

LCM(21,8621) = ( 21 × 8621 ) / 1

LCM(21,8621) = 181041 / 1

LCM(21,8621) = 181041


Lets's calculate GCF of 660,3356

2 660, 3356
2 330, 1678
165, 839

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 181041/4

Therefore the LCM of Fractions 21/660,8621/3356 is 181041/4
