Least Common Multiple of 688,860,990 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 688,860,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(688,860,990) = 2

common factors(in case of two or more numbers have common factors) = 860

GCF(688,860,990) x common factors =2 x 860 = 1720

LCM(688,860,990) = ( 688 × 860 × 990 ) / 1720

LCM(688,860,990) = 585763200 / 1720

LCM(688,860,990) = 340560

∴ Least Common Multiple of 688,860,990 is 340560
