Least Common Multiple of 90,21,80,775 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 90,21,80,775 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,21,80,775) = 1

common factors(in case of two or more numbers have common factors) = 150

GCF(90,21,80,775) x common factors =1 x 150 = 150

LCM(90,21,80,775) = ( 90 × 21 × 80 × 775 ) / 150

LCM(90,21,80,775) = 117180000 / 150

LCM(90,21,80,775) = 781200

∴ Least Common Multiple of 90,21,80,775 is 781200
