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 39,457,290

Least Common Multiple of Numerators i.e. LCM of 39,457,290 is 5168670.

GCF of Denominators means GCF of 170,621,989 as per the given fractions.

GCF of 170,621,989 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 39,457,290

LCM of Fractions 39/170,457/621,290/989 is 5168670

Given numbers has no common factors except 1. So, there LCM is their product i.e 5168670

Least Common Multiple of 39,457,290 with GCF Formula

Least Common Multiple of 39,457,290 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 39,457,290 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(39,457,290) = 1

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

GCF(39,457,290) x common factors =1 x 1 = 1

LCM(39,457,290) = ( 39 × 457 × 290 ) / 1

LCM(39,457,290) = 5168670 / 1

LCM(39,457,290) = 5168670


Lets's calculate GCF of 170,621,989

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5168670/1

Therefore the LCM of Fractions 39/170,457/621,290/989 is 5168670
