Lets's calculate LCM of 642,4738

LCM of Fractions 642/421,4738/3171 is 1520898

2 642, 4738
321, 2369

∴ So the LCM of the given numbers is 2 x 321 x 2369 = 1520898

Least Common Multiple of 642,4738 with GCF Formula

Least Common Multiple of 642,4738 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 642,4738 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,4738) = 2

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

GCF(642,4738) x common factors =2 x 1 = 2

LCM(642,4738) = ( 642 × 4738 ) / 2

LCM(642,4738) = 3041796 / 2

LCM(642,4738) = 1520898


Lets's calculate GCF of 421,3171

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1520898/1

Therefore the LCM of Fractions 642/421,4738/3171 is 1520898
