Greatest Common Factor
We found the factors 18,78,417 . The biggest common factor number is the GCF number.
So the greatest common factor 18,78,417 is 3.
Lets's calculate LCM of 732,463,813
3 | 732, 463, 813 |
244, 463, 271 |
∴ So the LCM of the given numbers is 3 x 244 x 463 x 271 = 91846236
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/91846236
Therefore, the GCF of Fractions 18/732,78/463,417/813 is 3/91846236
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 732,463,813 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(732,463,813) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(732,463,813) x common factors =1 x 3 = 3
LCM(732,463,813) = ( 732 × 463 × 813 ) / 3
LCM(732,463,813) = 275538708 / 3
LCM(732,463,813) = 91846236
