1,2,4,8,16,29,32,58,116,232,464,928
Greatest Common Factor
We found the factors 17,447,928 . The biggest common factor number is the GCF number.
So the greatest common factor 17,447,928 is 1.
Lets's calculate LCM of 286,858,904
2 | 286, 858, 904 |
11 | 143, 429, 452 |
13 | 13, 39, 452 |
1, 3, 452 |
∴ So the LCM of the given numbers is 2 x 11 x 13 x 1 x 3 x 452 = 387816
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/387816
Therefore, the GCF of Fractions 17/286,447/858,928/904 is 1/387816
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 286,858,904 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(286,858,904) = 2
common factors(in case of two or more numbers have common factors) = 286
GCF(286,858,904) x common factors =2 x 286 = 572
LCM(286,858,904) = ( 286 × 858 × 904 ) / 572
LCM(286,858,904) = 221830752 / 572
LCM(286,858,904) = 387816
