Lets's calculate LCM of 797,860
Given numbers has no common factors except 1. So, there LCM is their product i.e 685420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/685420
Therefore, the GCF of Fractions 644/797,745/860 is 1/685420
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 797,860 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(797,860) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(797,860) x common factors =1 x 1 = 1
LCM(797,860) = ( 797 × 860 ) / 1
LCM(797,860) = 685420 / 1
LCM(797,860) = 685420
