We found the factors 531,445,693 . The biggest common factor number is the GCF number.
So the greatest common factor 531,445,693 is 1.
Lets's calculate LCM of 831,257,474
3 | 831, 257, 474 |
277, 257, 158 |
∴ So the LCM of the given numbers is 3 x 277 x 257 x 158 = 33743586
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33743586
Therefore, the GCF of Fractions 531/831,445/257,693/474 is 1/33743586
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 831,257,474 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(831,257,474) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(831,257,474) x common factors =1 x 3 = 3
LCM(831,257,474) = ( 831 × 257 × 474 ) / 3
LCM(831,257,474) = 101230758 / 3
LCM(831,257,474) = 33743586
