Lowest Common Multiple of 80,71,480 using Common Division

2	80, 71, 480
2	40, 71, 240
2	20, 71, 120
2	10, 71, 60
5	5, 71, 30
	1, 71, 6

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 1 x 71 x 6 = 34080

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34080

Least Common Multiple of 80,71,480 with GCF Formula

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 80,71,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,71,480) = 1

common factors(in case of two or more numbers have common factors) = 80

GCF(80,71,480) x common factors =1 x 80 = 80

LCM(80,71,480) = ( 80 × 71 × 480 ) / 80

LCM(80,71,480) = 2726400 / 80

LCM(80,71,480) = 34080
