So the greatest common factor 10,42,355 is 1.

Lets's calculate LCM of 80,48,330

2 80, 48, 330
2 40, 24, 165
2 20, 12, 165
2 10, 6, 165
3 5, 3, 165
5 5, 1, 55
1, 1, 11

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 1 x 11 = 2640

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2640

Therefore, the GCF of Fractions 10/80,42/48,355/330 is 1/2640

Least Common Multiple of 80,48,330 with GCF Formula

Least Common Multiple of 80,48,330 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 80,48,330 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,48,330) = 2

common factors(in case of two or more numbers have common factors) = 240

GCF(80,48,330) x common factors =2 x 240 = 480

LCM(80,48,330) = ( 80 × 48 × 330 ) / 480

LCM(80,48,330) = 1267200 / 480

LCM(80,48,330) = 2640
