Lets's calculate LCM of 438,592

LCM of Fractions 438/391,592/217 is 129648

2 438, 592
219, 296

∴ So the LCM of the given numbers is 2 x 219 x 296 = 129648

Least Common Multiple of 438,592 with GCF Formula

Least Common Multiple of 438,592 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 438,592 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(438,592) = 2

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

GCF(438,592) x common factors =2 x 1 = 2

LCM(438,592) = ( 438 × 592 ) / 2

LCM(438,592) = 259296 / 2

LCM(438,592) = 129648


Lets's calculate GCF of 391,217

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 129648/1

Therefore the LCM of Fractions 438/391,592/217 is 129648
