1,5,163,815
Factors of 7131
List of positive integer factors of 7131 that divides 7131 without a remainder.
1,3,2377,7131
Greatest Common Factor
We found the factors 815,7131 . The biggest common factor number is the GCF number.
So the greatest common factor 815,7131 is 1.
Lets's calculate LCM of 405,291
3 | 405, 291 |
135, 97 |
∴ So the LCM of the given numbers is 3 x 135 x 97 = 39285
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39285
Therefore, the GCF of Fractions 815/405,7131/291 is 1/39285
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 405,291 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(405,291) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(405,291) x common factors =3 x 1 = 3
LCM(405,291) = ( 405 × 291 ) / 3
LCM(405,291) = 117855 / 3
LCM(405,291) = 39285
