Least Common Multiple of 1785,4200 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 1785,4200 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1785,4200) = 105

common factors(in case of two or more numbers have common factors) = 1

GCF(1785,4200) x common factors =105 x 1 = 105

LCM(1785,4200) = ( 1785 × 4200 ) / 105

LCM(1785,4200) = 7497000 / 105

LCM(1785,4200) = 71400

∴ Least Common Multiple of 1785,4200 is 71400
