1,3,9,19,27,57,171,513
Factors of 471
List of positive integer factors of 471 that divides 471 without a remainder.
1,3,157,471
Greatest Common Factor
We found the factors 640,513,471 . The biggest common factor number is the GCF number.
So the greatest common factor 640,513,471 is 1.
Lets's calculate LCM of 41,51,807
3 | 41, 51, 807 |
41, 17, 269 |
∴ So the LCM of the given numbers is 3 x 41 x 17 x 269 = 562479
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/562479
Therefore, the GCF of Fractions 640/41,513/51,471/807 is 1/562479
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 41,51,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(41,51,807) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(41,51,807) x common factors =1 x 3 = 3
LCM(41,51,807) = ( 41 × 51 × 807 ) / 3
LCM(41,51,807) = 1687437 / 3
LCM(41,51,807) = 562479
