Lets's calculate LCM of 396,990
2 | 396, 990 |
3 | 198, 495 |
3 | 66, 165 |
11 | 22, 55 |
2, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 2 x 5 = 1980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1980
Therefore, the GCF of Fractions 692/396,7706/990 is 2/1980
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 396,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(396,990) = 198
common factors(in case of two or more numbers have common factors) = 1
GCF(396,990) x common factors =198 x 1 = 198
LCM(396,990) = ( 396 × 990 ) / 198
LCM(396,990) = 392040 / 198
LCM(396,990) = 1980
