Lets's calculate LCM of 768,9990
2 | 768, 9990 |
3 | 384, 4995 |
128, 1665 |
∴ So the LCM of the given numbers is 2 x 3 x 128 x 1665 = 1278720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1278720
Therefore, the GCF of Fractions 515/768,7814/9990 is 1/1278720
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 768,9990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,9990) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(768,9990) x common factors =6 x 1 = 6
LCM(768,9990) = ( 768 × 9990 ) / 6
LCM(768,9990) = 7672320 / 6
LCM(768,9990) = 1278720
