Least Common Multiple of 644/19,393/42,804/133

Given numbers are 644/19,393/42,804/133

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 644,393,804

Least Common Multiple of Numerators i.e. LCM of 644,393,804 is 16957164.

GCF of Denominators means GCF of 19,42,133 as per the given fractions.

GCF of 19,42,133 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 644,393,804

LCM of Fractions 644/19,393/42,804/133 is 16957164

2 644, 393, 804
2 322, 393, 402
3 161, 393, 201
161, 131, 67

∴ So the LCM of the given numbers is 2 x 2 x 3 x 161 x 131 x 67 = 16957164

Least Common Multiple of 644,393,804 with GCF Formula

Least Common Multiple of 644,393,804 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 644,393,804 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(644,393,804) = 1

common factors(in case of two or more numbers have common factors) = 12

GCF(644,393,804) x common factors =1 x 12 = 12

LCM(644,393,804) = ( 644 × 393 × 804 ) / 12

LCM(644,393,804) = 203485968 / 12

LCM(644,393,804) = 16957164


Lets's calculate GCF of 19,42,133

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 16957164/1

Therefore the LCM of Fractions 644/19,393/42,804/133 is 16957164
