Greatest Common Factor
We found the factors 728,685 . The biggest common factor number is the GCF number.
So the greatest common factor 728,685 is 1.
Lets's calculate LCM of 92,384
2 | 92, 384 |
2 | 46, 192 |
23, 96 |
∴ So the LCM of the given numbers is 2 x 2 x 23 x 96 = 8832
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8832
Therefore, the GCF of Fractions 728/92,685/384 is 1/8832
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 92,384 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,384) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(92,384) x common factors =4 x 1 = 4
LCM(92,384) = ( 92 × 384 ) / 4
LCM(92,384) = 35328 / 4
LCM(92,384) = 8832
