Lets's calculate LCM of 789,817

LCM of Fractions 789/678,817/409 is 644613

Given numbers has no common factors except 1. So, there LCM is their product i.e 644613

Least Common Multiple of 789,817 with GCF Formula

Least Common Multiple of 789,817 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 789,817 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(789,817) = 1

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

GCF(789,817) x common factors =1 x 1 = 1

LCM(789,817) = ( 789 × 817 ) / 1

LCM(789,817) = 644613 / 1

LCM(789,817) = 644613


Lets's calculate GCF of 678,409

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 644613/1

Therefore the LCM of Fractions 789/678,817/409 is 644613
