Lets's calculate LCM of 542,845
Given numbers has no common factors except 1. So, there LCM is their product i.e 457990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/457990
Therefore, the GCF of Fractions 656/542,355/845 is 1/457990
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 542,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(542,845) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(542,845) x common factors =1 x 1 = 1
LCM(542,845) = ( 542 × 845 ) / 1
LCM(542,845) = 457990 / 1
LCM(542,845) = 457990
