Least Common Multiple of 12,49,63,621 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 12,49,63,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,49,63,621) = 1

common factors(in case of two or more numbers have common factors) = 189

GCF(12,49,63,621) x common factors =1 x 189 = 189

LCM(12,49,63,621) = ( 12 × 49 × 63 × 621 ) / 189

LCM(12,49,63,621) = 23004324 / 189

LCM(12,49,63,621) = 121716

∴ Least Common Multiple of 12,49,63,621 is 121716
