Lets's calculate LCM of 7849,3989

LCM of Fractions 7849/82,3989/970 is 31309661/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 31309661

Least Common Multiple of 7849,3989 with GCF Formula

Least Common Multiple of 7849,3989 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 7849,3989 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7849,3989) = 1

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

GCF(7849,3989) x common factors =1 x 1 = 1

LCM(7849,3989) = ( 7849 × 3989 ) / 1

LCM(7849,3989) = 31309661 / 1

LCM(7849,3989) = 31309661


Lets's calculate GCF of 82,970

2 82, 970
41, 485

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 31309661/2

Therefore the LCM of Fractions 7849/82,3989/970 is 31309661/2
