Lets's calculate LCM of 72,21,68,838

2 72, 21, 68, 838
2 36, 21, 34, 419
3 18, 21, 17, 419
6, 7, 17, 419

∴ So the LCM of the given numbers is 2 x 2 x 3 x 6 x 7 x 17 x 419 = 3589992

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3589992

Therefore, the GCF of Fractions 10/72,18/21,66/68,11/838 is 1/3589992

Least Common Multiple of 72,21,68,838 with GCF Formula

Least Common Multiple of 72,21,68,838 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 72,21,68,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,21,68,838) = 1

common factors(in case of two or more numbers have common factors) = 24

GCF(72,21,68,838) x common factors =1 x 24 = 24

LCM(72,21,68,838) = ( 72 × 21 × 68 × 838 ) / 24

LCM(72,21,68,838) = 86159808 / 24

LCM(72,21,68,838) = 3589992
