Lets's calculate LCM of 7721,6420

LCM of Fractions 7721/847,6420/1969 is 49568820/11

Given numbers has no common factors except 1. So, there LCM is their product i.e 49568820

Least Common Multiple of 7721,6420 with GCF Formula

Least Common Multiple of 7721,6420 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 7721,6420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7721,6420) = 1

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

GCF(7721,6420) x common factors =1 x 1 = 1

LCM(7721,6420) = ( 7721 × 6420 ) / 1

LCM(7721,6420) = 49568820 / 1

LCM(7721,6420) = 49568820


Lets's calculate GCF of 847,1969

11 847, 1969
77, 179

∴ So the GCF of the given numbers is 11 = 11

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 49568820/11

Therefore the LCM of Fractions 7721/847,6420/1969 is 49568820/11
