LCM of:

Least Common Multiple of 644/30,997/4020

Given numbers are 644/30,997/4020

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 644,997

Least Common Multiple of Numerators i.e. LCM of 644,997 is 642068.

GCF of Denominators means GCF of 30,4020 as per the given fractions.

GCF of 30,4020 is 30 as it is the largest common factor for these numbers.

Lets's calculate LCM of 644,997

LCM of Fractions 644/30,997/4020 is 642068/30

Given numbers has no common factors except 1. So, there LCM is their product i.e 642068

Least Common Multiple of 644,997 with GCF Formula

Least Common Multiple of 644,997 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 644,997 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(644,997) = 1

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

GCF(644,997) x common factors =1 x 1 = 1

LCM(644,997) = ( 644 × 997 ) / 1

LCM(644,997) = 642068 / 1

LCM(644,997) = 642068


Lets's calculate GCF of 30,4020

2 30, 4020
3 15, 2010
5 5, 670
1, 134

∴ So the GCF of the given numbers is 2 x 3 x 5 = 30

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 642068/30

Therefore the LCM of Fractions 644/30,997/4020 is 642068/30
