Least Common Multiple of 76,72,90,780 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 76,72,90,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(76,72,90,780) = 2

common factors(in case of two or more numbers have common factors) = 2160

GCF(76,72,90,780) x common factors =2 x 2160 = 4320

LCM(76,72,90,780) = ( 76 × 72 × 90 × 780 ) / 4320

LCM(76,72,90,780) = 384134400 / 4320

LCM(76,72,90,780) = 88920

∴ Least Common Multiple of 76,72,90,780 is 88920
