Lets's calculate LCM of 90,88,66,882
| 2 | 90, 88, 66, 882 |
| 3 | 45, 44, 33, 441 |
| 3 | 15, 44, 11, 147 |
| 11 | 5, 44, 11, 49 |
| 5, 4, 1, 49 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 5 x 4 x 1 x 49 = 194040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/194040

Least Common Multiple of 90,88,66,882 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 90,88,66,882 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,88,66,882) = 2
common factors(in case of two or more numbers have common factors) = 1188
GCF(90,88,66,882) x common factors =2 x 1188 = 2376
LCM(90,88,66,882) = ( 90 × 88 × 66 × 882 ) / 2376
LCM(90,88,66,882) = 461039040 / 2376
LCM(90,88,66,882) = 194040
