Given numbers are 81/641,74/702,658/355

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 81,74,658

Least Common Multiple of Numerators i.e. LCM of 81,74,658 is 1972026.

GCF of Denominators means GCF of 641,702,355 as per the given fractions.

GCF of 641,702,355 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,74,658

LCM of Fractions 81/641,74/702,658/355 is 1972026

2 81, 74, 658
81, 37, 329

∴ So the LCM of the given numbers is 2 x 81 x 37 x 329 = 1972026

Least Common Multiple of 81,74,658 with GCF Formula

Least Common Multiple of 81,74,658 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 81,74,658 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,74,658) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(81,74,658) x common factors =1 x 2 = 2

LCM(81,74,658) = ( 81 × 74 × 658 ) / 2

LCM(81,74,658) = 3944052 / 2

LCM(81,74,658) = 1972026


Lets's calculate GCF of 641,702,355

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1972026/1

Therefore the LCM of Fractions 81/641,74/702,658/355 is 1972026
