Lets's calculate LCM of 19,91,91,989
| 7 | 19, 91, 91, 989 |
| 13 | 19, 13, 13, 989 |
| 19, 1, 1, 989 |
∴ So the LCM of the given numbers is 7 x 13 x 19 x 1 x 1 x 989 = 1709981
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1709981
Therefore, the GCF of Fractions 10/19,57/91,50/91,18/989 is 1/1709981
Least Common Multiple of 19,91,91,989 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 19,91,91,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,91,91,989) = 1
common factors(in case of two or more numbers have common factors) = 91
GCF(19,91,91,989) x common factors =1 x 91 = 91
LCM(19,91,91,989) = ( 19 × 91 × 91 × 989 ) / 91
LCM(19,91,91,989) = 155608271 / 91
LCM(19,91,91,989) = 1709981
