Lets's calculate LCM of 90,44,552

2 90, 44, 552
2 45, 22, 276
3 45, 11, 138
15, 11, 46

∴ So the LCM of the given numbers is 2 x 2 x 3 x 15 x 11 x 46 = 91080

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91080

Therefore, the GCF of Fractions 641/90,638/44,428/552 is 1/91080

Least Common Multiple of 90,44,552 with GCF Formula

Least Common Multiple of 90,44,552 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 90,44,552 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,44,552) = 2

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

GCF(90,44,552) x common factors =2 x 12 = 24

LCM(90,44,552) = ( 90 × 44 × 552 ) / 24

LCM(90,44,552) = 2185920 / 24

LCM(90,44,552) = 91080
