Least Common Multiple of 405,60,684 with GCF Formula

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 405,60,684 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(405,60,684) = 3

common factors(in case of two or more numbers have common factors) = 180

GCF(405,60,684) x common factors =3 x 180 = 540

LCM(405,60,684) = ( 405 × 60 × 684 ) / 540

LCM(405,60,684) = 16621200 / 540

LCM(405,60,684) = 30780

∴ Least Common Multiple of 405,60,684 is 30780
