Lets's calculate LCM of 110,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 72710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72710
Therefore, the GCF of Fractions 391/110,392/661 is 1/72710
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 110,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(110,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(110,661) x common factors =1 x 1 = 1
LCM(110,661) = ( 110 × 661 ) / 1
LCM(110,661) = 72710 / 1
LCM(110,661) = 72710
