Greatest Common Factor
We found the factors 782,398,643 . The biggest common factor number is the GCF number.
So the greatest common factor 782,398,643 is 1.
Lets's calculate LCM of 534,750,388
2 | 534, 750, 388 |
3 | 267, 375, 194 |
89, 125, 194 |
∴ So the LCM of the given numbers is 2 x 3 x 89 x 125 x 194 = 12949500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12949500
Therefore, the GCF of Fractions 782/534,398/750,643/388 is 1/12949500
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 534,750,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(534,750,388) = 2
common factors(in case of two or more numbers have common factors) = 6
GCF(534,750,388) x common factors =2 x 6 = 12
LCM(534,750,388) = ( 534 × 750 × 388 ) / 12
LCM(534,750,388) = 155394000 / 12
LCM(534,750,388) = 12949500
