Lets's calculate LCM of 320,399,480

2 320, 399, 480
2 160, 399, 240
2 80, 399, 120
2 40, 399, 60
2 20, 399, 30
3 10, 399, 15
5 10, 133, 5
2, 133, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 3 x 5 x 2 x 133 x 1 = 127680

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/127680

Least Common Multiple of 320,399,480 with GCF Formula

Least Common Multiple of 320,399,480 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 320,399,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(320,399,480) = 1

common factors(in case of two or more numbers have common factors) = 480

GCF(320,399,480) x common factors =1 x 480 = 480

LCM(320,399,480) = ( 320 × 399 × 480 ) / 480

LCM(320,399,480) = 61286400 / 480

LCM(320,399,480) = 127680
