Lets's calculate LCM of 660,360,421

2 660, 360, 421
2 330, 180, 421
3 165, 90, 421
5 55, 30, 421
11, 6, 421

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 11 x 6 x 421 = 1667160

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1667160

Therefore, the GCF of Fractions 73/660,63/360,455/421 is 1/1667160

Least Common Multiple of 660,360,421 with GCF Formula

Least Common Multiple of 660,360,421 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 660,360,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(660,360,421) = 1

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

GCF(660,360,421) x common factors =1 x 60 = 60

LCM(660,360,421) = ( 660 × 360 × 421 ) / 60

LCM(660,360,421) = 100029600 / 60

LCM(660,360,421) = 1667160
