So the greatest common factor 66,21,660 is 3.

Lets's calculate LCM of 60,33,911

3 60, 33, 911
20, 11, 911

∴ So the LCM of the given numbers is 3 x 20 x 11 x 911 = 601260

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/601260

Therefore, the GCF of Fractions 66/60,21/33,660/911 is 3/601260

Least Common Multiple of 60,33,911 with GCF Formula

Least Common Multiple of 60,33,911 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 60,33,911 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(60,33,911) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(60,33,911) x common factors =1 x 3 = 3

LCM(60,33,911) = ( 60 × 33 × 911 ) / 3

LCM(60,33,911) = 1803780 / 3

LCM(60,33,911) = 601260
