So the greatest common factor 27,93,720 is 3.


Lets's calculate LCM of 90,45,730

2 90, 45, 730
3 45, 45, 365
3 15, 15, 365
5 5, 5, 365
1, 1, 73

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 1 x 1 x 73 = 6570

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6570

Therefore, the GCF of Fractions 27/90,93/45,720/730 is 3/6570

Least Common Multiple of 90,45,730 with GCF Formula

Least Common Multiple of 90,45,730 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 90,45,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,45,730) = 5

common factors(in case of two or more numbers have common factors) = 90

GCF(90,45,730) x common factors =5 x 90 = 450

LCM(90,45,730) = ( 90 × 45 × 730 ) / 450

LCM(90,45,730) = 2956500 / 450

LCM(90,45,730) = 6570
