Greatest Common Factor
We found the factors 504,171 . The biggest common factor number is the GCF number.
So the greatest common factor 504,171 is 9.
Lets's calculate LCM of 108,351
3 | 108, 351 |
3 | 36, 117 |
3 | 12, 39 |
4, 13 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 4 x 13 = 1404
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1404
Therefore, the GCF of Fractions 504/108,171/351 is 9/1404
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 108,351 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(108,351) = 27
common factors(in case of two or more numbers have common factors) = 1
GCF(108,351) x common factors =27 x 1 = 27
LCM(108,351) = ( 108 × 351 ) / 27
LCM(108,351) = 37908 / 27
LCM(108,351) = 1404
