Lets's calculate LCM of 76,42,561,441
| 2 | 76, 42, 561, 441 |
| 3 | 38, 21, 561, 441 |
| 7 | 38, 7, 187, 147 |
| 38, 1, 187, 21 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 38 x 1 x 187 x 21 = 6267492
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6267492

Least Common Multiple of 76,42,561,441 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 76,42,561,441 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,42,561,441) = 1
common factors(in case of two or more numbers have common factors) = 126
GCF(76,42,561,441) x common factors =1 x 126 = 126
LCM(76,42,561,441) = ( 76 × 42 × 561 × 441 ) / 126
LCM(76,42,561,441) = 789703992 / 126
LCM(76,42,561,441) = 6267492
