Lets's calculate LCM of 394,618
2 | 394, 618 |
197, 309 |
∴ So the LCM of the given numbers is 2 x 197 x 309 = 121746
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/121746
Therefore, the GCF of Fractions 555/394,531/618 is 3/121746
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 394,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(394,618) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(394,618) x common factors =2 x 1 = 2
LCM(394,618) = ( 394 × 618 ) / 2
LCM(394,618) = 243492 / 2
LCM(394,618) = 121746
