Lets's calculate LCM of 7990,9978

LCM of Fractions 7990/910,9978/978 is 19931055

2 7990, 9978
3995, 4989

∴ So the LCM of the given numbers is 2 x 3995 x 4989 = 39862110

Least Common Multiple of 7990,9978 with GCF Formula

Least Common Multiple of 7990,9978 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 7990,9978 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7990,9978) = 2

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

GCF(7990,9978) x common factors =2 x 1 = 2

LCM(7990,9978) = ( 7990 × 9978 ) / 2

LCM(7990,9978) = 79724220 / 2

LCM(7990,9978) = 39862110


Lets's calculate GCF of 910,978

2 910, 978
455, 489

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 39862110/2

Therefore the LCM of Fractions 7990/910,9978/978 is 19931055
