So the greatest common factor 45,30,684 is 3.

Lets's calculate LCM of 66,47,928

2 66, 47, 928
33, 47, 464

∴ So the LCM of the given numbers is 2 x 33 x 47 x 464 = 1439328

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1439328

Therefore, the GCF of Fractions 45/66,30/47,684/928 is 3/1439328

Least Common Multiple of 66,47,928 with GCF Formula

Least Common Multiple of 66,47,928 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 66,47,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,47,928) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(66,47,928) x common factors =1 x 2 = 2

LCM(66,47,928) = ( 66 × 47 × 928 ) / 2

LCM(66,47,928) = 2878656 / 2

LCM(66,47,928) = 1439328
