Lets's calculate LCM of 120,1455
3 | 120, 1455 |
5 | 40, 485 |
8, 97 |
∴ So the LCM of the given numbers is 3 x 5 x 8 x 97 = 11640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11640
Therefore, the GCF of Fractions 1634/120,7987/1455 is 1/11640
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 120,1455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(120,1455) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(120,1455) x common factors =15 x 1 = 15
LCM(120,1455) = ( 120 × 1455 ) / 15
LCM(120,1455) = 174600 / 15
LCM(120,1455) = 11640
