Least Common Multiple of 81/59,538/78,693/641

Given numbers are 81/59,538/78,693/641

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 81,538,693

Least Common Multiple of Numerators i.e. LCM of 81,538,693 is 3355506.

GCF of Denominators means GCF of 59,78,641 as per the given fractions.

GCF of 59,78,641 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,538,693

LCM of Fractions 81/59,538/78,693/641 is 3355506

3 81, 538, 693
3 27, 538, 231
9, 538, 77

∴ So the LCM of the given numbers is 3 x 3 x 9 x 538 x 77 = 3355506

Least Common Multiple of 81,538,693 with GCF Formula

Least Common Multiple of 81,538,693 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 81,538,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,538,693) = 1

common factors(in case of two or more numbers have common factors) = 9

GCF(81,538,693) x common factors =1 x 9 = 9

LCM(81,538,693) = ( 81 × 538 × 693 ) / 9

LCM(81,538,693) = 30199554 / 9

LCM(81,538,693) = 3355506


Lets's calculate GCF of 59,78,641

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3355506/1

Therefore the LCM of Fractions 81/59,538/78,693/641 is 3355506
