Lets's calculate LCM of 45,12,45,164
| 2 | 45, 12, 45, 164 |
| 2 | 45, 6, 45, 82 |
| 3 | 45, 3, 45, 41 |
| 3 | 15, 1, 15, 41 |
| 5 | 5, 1, 5, 41 |
| 1, 1, 1, 41 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 1 x 1 x 1 x 41 = 7380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7380

Least Common Multiple of 45,12,45,164 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 45,12,45,164 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,12,45,164) = 1
common factors(in case of two or more numbers have common factors) = 540
GCF(45,12,45,164) x common factors =1 x 540 = 540
LCM(45,12,45,164) = ( 45 × 12 × 45 × 164 ) / 540
LCM(45,12,45,164) = 3985200 / 540
LCM(45,12,45,164) = 7380
