Lets's calculate LCM of 270,172,405

2 270, 172, 405
3 135, 86, 405
3 45, 86, 135
3 15, 86, 45
5 5, 86, 15
1, 86, 3

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 5 x 1 x 86 x 3 = 69660

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/69660

Least Common Multiple of 270,172,405 with GCF Formula

Least Common Multiple of 270,172,405 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 270,172,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(270,172,405) = 1

common factors(in case of two or more numbers have common factors) = 270

GCF(270,172,405) x common factors =1 x 270 = 270

LCM(270,172,405) = ( 270 × 172 × 405 ) / 270

LCM(270,172,405) = 18808200 / 270

LCM(270,172,405) = 69660
