Therefore, the GCF of Fractions 9903/402,7191/382 is 3/76782
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 402,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,382) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(402,382) x common factors =2 x 1 = 2
LCM(402,382) = ( 402 × 382 ) / 2
LCM(402,382) = 153564 / 2
LCM(402,382) = 76782
