Lets's calculate LCM of 198,450
2 | 198, 450 |
3 | 99, 225 |
3 | 33, 75 |
11, 25 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 25 = 4950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4950
Therefore, the GCF of Fractions 401/198,378/450 is 1/4950
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 198,450 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(198,450) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(198,450) x common factors =18 x 1 = 18
LCM(198,450) = ( 198 × 450 ) / 18
LCM(198,450) = 89100 / 18
LCM(198,450) = 4950
