Least Common Multiple of 420,284 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 420,284 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,284) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(420,284) x common factors =4 x 1 = 4
LCM(420,284) = ( 420 × 284 ) / 4
LCM(420,284) = 119280 / 4
LCM(420,284) = 29820
