So the greatest common factor 68,15,899 is 1.
Lets's calculate LCM of 242,310,990
2 | 242, 310, 990 |
5 | 121, 155, 495 |
11 | 121, 31, 99 |
11, 31, 9 |
∴ So the LCM of the given numbers is 2 x 5 x 11 x 11 x 31 x 9 = 337590
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/337590
Therefore, the GCF of Fractions 68/242,15/310,899/990 is 1/337590
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 242,310,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(242,310,990) = 2
common factors(in case of two or more numbers have common factors) = 110
GCF(242,310,990) x common factors =2 x 110 = 220
LCM(242,310,990) = ( 242 × 310 × 990 ) / 220
LCM(242,310,990) = 74269800 / 220
LCM(242,310,990) = 337590
