Lets's calculate LCM of 3998,7449

LCM of Fractions 3998/409,7449/434 is 29781102

Given numbers has no common factors except 1. So, there LCM is their product i.e 29781102

Least Common Multiple of 3998,7449 with GCF Formula

Least Common Multiple of 3998,7449 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 3998,7449 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3998,7449) = 1

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

GCF(3998,7449) x common factors =1 x 1 = 1

LCM(3998,7449) = ( 3998 × 7449 ) / 1

LCM(3998,7449) = 29781102 / 1

LCM(3998,7449) = 29781102


Lets's calculate GCF of 409,434

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 29781102/1

Therefore the LCM of Fractions 3998/409,7449/434 is 29781102
