Lets's calculate LCM of 17,385,828

LCM of Fractions 17/720,385/769,828/861 is 5419260

Given numbers has no common factors except 1. So, there LCM is their product i.e 5419260

Least Common Multiple of 17,385,828 with GCF Formula

Least Common Multiple of 17,385,828 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 17,385,828 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,385,828) = 1

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

GCF(17,385,828) x common factors =1 x 1 = 1

LCM(17,385,828) = ( 17 × 385 × 828 ) / 1

LCM(17,385,828) = 5419260 / 1

LCM(17,385,828) = 5419260


Lets's calculate GCF of 720,769,861

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5419260/1

Therefore the LCM of Fractions 17/720,385/769,828/861 is 5419260
