Least Common Multiple of 87,51,72,391

Least Common Multiple (LCM) of 87,51,72,391 is 816408

3	87, 51, 72, 391
17	29, 17, 24, 391
	29, 1, 24, 23

∴ So the LCM of the given numbers is 3 x 17 x 29 x 1 x 24 x 23 = 816408

Least Common Multiple of 87,51,72,391 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 87,51,72,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,51,72,391) = 1

common factors(in case of two or more numbers have common factors) = 153

GCF(87,51,72,391) x common factors =1 x 153 = 153

LCM(87,51,72,391) = ( 87 × 51 × 72 × 391 ) / 153

LCM(87,51,72,391) = 124910424 / 153

LCM(87,51,72,391) = 816408

∴ Least Common Multiple of 87,51,72,391 is 816408
