Lets's calculate LCM of 686,8790

LCM of Fractions 686/620,8790/938 is 1507485

2 686, 8790
343, 4395

∴ So the LCM of the given numbers is 2 x 343 x 4395 = 3014970

Least Common Multiple of 686,8790 with GCF Formula

Least Common Multiple of 686,8790 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 686,8790 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(686,8790) = 2

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

GCF(686,8790) x common factors =2 x 1 = 2

LCM(686,8790) = ( 686 × 8790 ) / 2

LCM(686,8790) = 6029940 / 2

LCM(686,8790) = 3014970


Lets's calculate GCF of 620,938

2 620, 938
310, 469

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3014970/2

Therefore the LCM of Fractions 686/620,8790/938 is 1507485
