Lets's calculate LCM of 90,20,411

2 90, 20, 411
3 45, 10, 411
5 15, 10, 137
3, 2, 137

∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 2 x 137 = 24660

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24660

Therefore, the GCF of Fractions 78/90,59/20,772/411 is 1/24660

Least Common Multiple of 90,20,411 with GCF Formula

Least Common Multiple of 90,20,411 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 90,20,411 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,20,411) = 1

common factors(in case of two or more numbers have common factors) = 30

GCF(90,20,411) x common factors =1 x 30 = 30

LCM(90,20,411) = ( 90 × 20 × 411 ) / 30

LCM(90,20,411) = 739800 / 30

LCM(90,20,411) = 24660
