Lets's calculate LCM of 648,120
2 | 648, 120 |
2 | 324, 60 |
2 | 162, 30 |
3 | 81, 15 |
27, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 27 x 5 = 3240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 47/3240
Therefore, the GCF of Fractions 799/648,470/120 is 47/3240
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 648,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(648,120) = 24
common factors(in case of two or more numbers have common factors) = 1
GCF(648,120) x common factors =24 x 1 = 24
LCM(648,120) = ( 648 × 120 ) / 24
LCM(648,120) = 77760 / 24
LCM(648,120) = 3240
