Lets's calculate LCM of 51,77,77,726
| 3 | 51, 77, 77, 726 |
| 7 | 17, 77, 77, 242 |
| 11 | 17, 11, 11, 242 |
| 17, 1, 1, 22 |
∴ So the LCM of the given numbers is 3 x 7 x 11 x 17 x 1 x 1 x 22 = 86394
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/86394

Least Common Multiple of 51,77,77,726 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 51,77,77,726 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,77,77,726) = 1
common factors(in case of two or more numbers have common factors) = 2541
GCF(51,77,77,726) x common factors =1 x 2541 = 2541
LCM(51,77,77,726) = ( 51 × 77 × 77 × 726 ) / 2541
LCM(51,77,77,726) = 219527154 / 2541
LCM(51,77,77,726) = 86394
