Greatest Common Factor
We found the factors 61,472,655 . The biggest common factor number is the GCF number.
So the greatest common factor 61,472,655 is 1.
Lets's calculate LCM of 78,24,857
2 | 78, 24, 857 |
3 | 39, 12, 857 |
13, 4, 857 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 4 x 857 = 267384
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/267384
Therefore, the GCF of Fractions 61/78,472/24,655/857 is 1/267384
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 78,24,857 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,24,857) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(78,24,857) x common factors =1 x 6 = 6
LCM(78,24,857) = ( 78 × 24 × 857 ) / 6
LCM(78,24,857) = 1604304 / 6
LCM(78,24,857) = 267384
