Greatest Common Factor
We found the factors 787,153 . The biggest common factor number is the GCF number.
So the greatest common factor 787,153 is 1.
Lets's calculate LCM of 658,956
2 | 658, 956 |
329, 478 |
∴ So the LCM of the given numbers is 2 x 329 x 478 = 314524
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/314524
Therefore, the GCF of Fractions 787/658,153/956 is 1/314524
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 658,956 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(658,956) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(658,956) x common factors =2 x 1 = 2
LCM(658,956) = ( 658 × 956 ) / 2
LCM(658,956) = 629048 / 2
LCM(658,956) = 314524
