Greatest Common Factor
We found the factors 330,515 . The biggest common factor number is the GCF number.
So the greatest common factor 330,515 is 5.
Lets's calculate LCM of 802,458
2 | 802, 458 |
401, 229 |
∴ So the LCM of the given numbers is 2 x 401 x 229 = 183658
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/183658
Therefore, the GCF of Fractions 330/802,515/458 is 5/183658
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 802,458 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(802,458) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(802,458) x common factors =2 x 1 = 2
LCM(802,458) = ( 802 × 458 ) / 2
LCM(802,458) = 367316 / 2
LCM(802,458) = 183658
