So the greatest common factor 756,798 is 42.
Lets's calculate LCM of 922,812
2 | 922, 812 |
461, 406 |
∴ So the LCM of the given numbers is 2 x 461 x 406 = 374332
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 42/374332
Therefore, the GCF of Fractions 756/922,798/812 is 42/374332
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 922,812 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(922,812) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(922,812) x common factors =2 x 1 = 2
LCM(922,812) = ( 922 × 812 ) / 2
LCM(922,812) = 748664 / 2
LCM(922,812) = 374332
