Lets's calculate LCM of 642,6405

LCM of Fractions 642/516,6405/128 is 1370670/4

3 642, 6405
214, 2135

∴ So the LCM of the given numbers is 3 x 214 x 2135 = 1370670

Least Common Multiple of 642,6405 with GCF Formula

Least Common Multiple of 642,6405 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 642,6405 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,6405) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(642,6405) x common factors =3 x 1 = 3

LCM(642,6405) = ( 642 × 6405 ) / 3

LCM(642,6405) = 4112010 / 3

LCM(642,6405) = 1370670


Lets's calculate GCF of 516,128

2 516, 128
2 258, 64
129, 32

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1370670/4

Therefore the LCM of Fractions 642/516,6405/128 is 1370670/4
