So the greatest common factor 720,656 is 16.
Lets's calculate LCM of 623,274
Given numbers has no common factors except 1. So, there LCM is their product i.e 170702
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/170702
Therefore, the GCF of Fractions 720/623,656/274 is 16/170702
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 623,274 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(623,274) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(623,274) x common factors =1 x 1 = 1
LCM(623,274) = ( 623 × 274 ) / 1
LCM(623,274) = 170702 / 1
LCM(623,274) = 170702
