Greatest Common Factor

We found the factors 800,730,457 . The biggest common factor number is the GCF number.
So the greatest common factor 800,730,457 is 1.

Lets's calculate LCM of 40,54,915

2 40, 54, 915
3 20, 27, 915
5 20, 9, 305
4, 9, 61

∴ So the LCM of the given numbers is 2 x 3 x 5 x 4 x 9 x 61 = 65880

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/65880

Therefore, the GCF of Fractions 800/40,730/54,457/915 is 1/65880

Least Common Multiple of 40,54,915 with GCF Formula

Least Common Multiple of 40,54,915 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 40,54,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,54,915) = 1

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

GCF(40,54,915) x common factors =1 x 30 = 30

LCM(40,54,915) = ( 40 × 54 × 915 ) / 30

LCM(40,54,915) = 1976400 / 30

LCM(40,54,915) = 65880
