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 819,546 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(819,546) = 273
common factors(in case of two or more numbers have common factors) = 1
GCF(819,546) x common factors =273 x 1 = 273
LCM(819,546) = ( 819 × 546 ) / 273
LCM(819,546) = 447174 / 273
LCM(819,546) = 1638
