Least Common Multiple of 60,81,810 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 60,81,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,81,810) = 3
common factors(in case of two or more numbers have common factors) = 810
GCF(60,81,810) x common factors =3 x 810 = 2430
LCM(60,81,810) = ( 60 × 81 × 810 ) / 2430
LCM(60,81,810) = 3936600 / 2430
LCM(60,81,810) = 1620
