Given numbers are 490/40,397/81,207/690

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 490,397,207

Least Common Multiple of Numerators i.e. LCM of 490,397,207 is 40267710.

GCF of Denominators means GCF of 40,81,690 as per the given fractions.

GCF of 40,81,690 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 490,397,207

LCM of Fractions 490/40,397/81,207/690 is 40267710

Given numbers has no common factors except 1. So, there LCM is their product i.e 40267710

Least Common Multiple of 490,397,207 with GCF Formula

Least Common Multiple of 490,397,207 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 490,397,207 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(490,397,207) = 1

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

GCF(490,397,207) x common factors =1 x 1 = 1

LCM(490,397,207) = ( 490 × 397 × 207 ) / 1

LCM(490,397,207) = 40267710 / 1

LCM(490,397,207) = 40267710


Lets's calculate GCF of 40,81,690

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 40267710/1

Therefore the LCM of Fractions 490/40,397/81,207/690 is 40267710
