Lets's calculate LCM of 660,344
2 | 660, 344 |
2 | 330, 172 |
165, 86 |
∴ So the LCM of the given numbers is 2 x 2 x 165 x 86 = 56760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/56760
Therefore, the GCF of Fractions 517/660,7788/344 is 11/56760
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 660,344 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(660,344) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(660,344) x common factors =4 x 1 = 4
LCM(660,344) = ( 660 × 344 ) / 4
LCM(660,344) = 227040 / 4
LCM(660,344) = 56760
