Lets's calculate LCM of 407,487,821

LCM of Fractions 407/16,487/97,821/399 is 162729589

Given numbers has no common factors except 1. So, there LCM is their product i.e 162729589

Least Common Multiple of 407,487,821 with GCF Formula

Least Common Multiple of 407,487,821 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 407,487,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(407,487,821) = 1

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

GCF(407,487,821) x common factors =1 x 1 = 1

LCM(407,487,821) = ( 407 × 487 × 821 ) / 1

LCM(407,487,821) = 162729589 / 1

LCM(407,487,821) = 162729589


Lets's calculate GCF of 16,97,399

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 162729589/1

Therefore the LCM of Fractions 407/16,487/97,821/399 is 162729589
