Least Common Multiple of 68,12,90 with GCF Formula

### Least Common Multiple of 68,12,90 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 68,12,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,12,90) = 2

common factors(in case of two or more numbers have common factors) = 12

GCF(68,12,90) x common factors =2 x 12 = 24

LCM(68,12,90) = ( 68 × 12 × 90 ) / 24

LCM(68,12,90) = 73440 / 24

LCM(68,12,90) = 3060

Lets's calculate GCF of 68,56,399

### Greatest Common Factor (GCF) of 68,56,399 By Common Division

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3060/1

Therefore the LCM of Fractions 68/68,12/56,90/399 is 3060
