Lets's calculate LCM of 85,68,52,533
| 2 | 85, 68, 52, 533 |
| 2 | 85, 34, 26, 533 |
| 13 | 85, 17, 13, 533 |
| 17 | 85, 17, 1, 41 |
| 5, 1, 1, 41 |
∴ So the LCM of the given numbers is 2 x 2 x 13 x 17 x 5 x 1 x 1 x 41 = 181220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/181220

Least Common Multiple of 85,68,52,533 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 85,68,52,533 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,68,52,533) = 1
common factors(in case of two or more numbers have common factors) = 884
GCF(85,68,52,533) x common factors =1 x 884 = 884
LCM(85,68,52,533) = ( 85 × 68 × 52 × 533 ) / 884
LCM(85,68,52,533) = 160198480 / 884
LCM(85,68,52,533) = 181220
