Therefore, the GCF of Fractions 728/81,615/865 is 1/70065
Least Common Multiple of 81,865 with GCF Formula
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 81,865 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,865) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,865) x common factors =1 x 1 = 1
LCM(81,865) = ( 81 × 865 ) / 1
LCM(81,865) = 70065 / 1
LCM(81,865) = 70065
