Lets's calculate LCM of 91,81,781

LCM of Fractions 91/408,81/873,781/890 is 5756751

Given numbers has no common factors except 1. So, there LCM is their product i.e 5756751

Least Common Multiple of 91,81,781 with GCF Formula

Least Common Multiple of 91,81,781 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 91,81,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,81,781) = 1

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

GCF(91,81,781) x common factors =1 x 1 = 1

LCM(91,81,781) = ( 91 × 81 × 781 ) / 1

LCM(91,81,781) = 5756751 / 1

LCM(91,81,781) = 5756751


Lets's calculate GCF of 408,873,890

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5756751/1

Therefore the LCM of Fractions 91/408,81/873,781/890 is 5756751
