Lets's calculate LCM of 665,7390

LCM of Fractions 665/128,7390/920 is 982870/8

5 665, 7390
133, 1478

∴ So the LCM of the given numbers is 5 x 133 x 1478 = 982870

Least Common Multiple of 665,7390 with GCF Formula

Least Common Multiple of 665,7390 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 665,7390 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(665,7390) = 5

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

GCF(665,7390) x common factors =5 x 1 = 5

LCM(665,7390) = ( 665 × 7390 ) / 5

LCM(665,7390) = 4914350 / 5

LCM(665,7390) = 982870


Lets's calculate GCF of 128,920

2 128, 920
2 64, 460
2 32, 230
16, 115

∴ So the GCF of the given numbers is 2 x 2 x 2 = 8

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 982870/8

Therefore the LCM of Fractions 665/128,7390/920 is 982870/8
