Lets's calculate LCM of 288,810
2 | 288, 810 |
3 | 144, 405 |
3 | 48, 135 |
16, 45 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 16 x 45 = 12960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12960
Therefore, the GCF of Fractions 918/288,907/810 is 1/12960
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 288,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(288,810) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(288,810) x common factors =18 x 1 = 18
LCM(288,810) = ( 288 × 810 ) / 18
LCM(288,810) = 233280 / 18
LCM(288,810) = 12960
