Lets's calculate LCM of 40,60,510

2 40, 60, 510
2 20, 30, 255
3 10, 15, 255
5 10, 5, 85
2, 1, 17

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 2 x 1 x 17 = 2040

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2040

Therefore, the GCF of Fractions 861/40,417/60,186/510 is 3/2040

Least Common Multiple of 40,60,510 with GCF Formula

Least Common Multiple of 40,60,510 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 40,60,510 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,60,510) = 10

common factors(in case of two or more numbers have common factors) = 60

GCF(40,60,510) x common factors =10 x 60 = 600

LCM(40,60,510) = ( 40 × 60 × 510 ) / 600

LCM(40,60,510) = 1224000 / 600

LCM(40,60,510) = 2040
