Lets's calculate LCM of 330,810
2 | 330, 810 |
3 | 165, 405 |
5 | 55, 135 |
11, 27 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 11 x 27 = 8910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/8910
Therefore, the GCF of Fractions 637/330,616/810 is 7/8910
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 330,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(330,810) = 30
common factors(in case of two or more numbers have common factors) = 1
GCF(330,810) x common factors =30 x 1 = 30
LCM(330,810) = ( 330 × 810 ) / 30
LCM(330,810) = 267300 / 30
LCM(330,810) = 8910
