Lets's calculate LCM of 381,404,781

LCM of Fractions 381/851,404/556,781/398 is 120214644

Given numbers has no common factors except 1. So, there LCM is their product i.e 120214644

Least Common Multiple of 381,404,781 with GCF Formula

Least Common Multiple of 381,404,781 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 381,404,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(381,404,781) = 1

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

GCF(381,404,781) x common factors =1 x 1 = 1

LCM(381,404,781) = ( 381 × 404 × 781 ) / 1

LCM(381,404,781) = 120214644 / 1

LCM(381,404,781) = 120214644


Lets's calculate GCF of 851,556,398

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 120214644/1

Therefore the LCM of Fractions 381/851,404/556,781/398 is 120214644
