1,7,83,581
Factors of 257
List of positive integer factors of 257 that divides 257 without a remainder.
1,257
Greatest Common Factor
We found the factors 33,581,257 . The biggest common factor number is the GCF number.
So the greatest common factor 33,581,257 is 1.
Lets's calculate LCM of 819,645,815
3 | 819, 645, 815 |
5 | 273, 215, 815 |
273, 43, 163 |
∴ So the LCM of the given numbers is 3 x 5 x 273 x 43 x 163 = 28701855
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28701855
Therefore, the GCF of Fractions 33/819,581/645,257/815 is 1/28701855
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 819,645,815 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(819,645,815) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(819,645,815) x common factors =1 x 15 = 15
LCM(819,645,815) = ( 819 × 645 × 815 ) / 15
LCM(819,645,815) = 430527825 / 15
LCM(819,645,815) = 28701855
