Lets's calculate LCM of 687,7815

LCM of Fractions 687/371,7815/620 is 1789635

3 687, 7815
229, 2605

∴ So the LCM of the given numbers is 3 x 229 x 2605 = 1789635

Least Common Multiple of 687,7815 with GCF Formula

Least Common Multiple of 687,7815 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 687,7815 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(687,7815) = 3

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

GCF(687,7815) x common factors =3 x 1 = 3

LCM(687,7815) = ( 687 × 7815 ) / 3

LCM(687,7815) = 5368905 / 3

LCM(687,7815) = 1789635


Lets's calculate GCF of 371,620

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1789635/1

Therefore the LCM of Fractions 687/371,7815/620 is 1789635
