Least Common Multiple of 420,238,620 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 420,238,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,238,620) = 2

common factors(in case of two or more numbers have common factors) = 140

GCF(420,238,620) x common factors =2 x 140 = 280

LCM(420,238,620) = ( 420 × 238 × 620 ) / 280

LCM(420,238,620) = 61975200 / 280

LCM(420,238,620) = 221340

∴ Least Common Multiple of 420,238,620 is 221340
