Least Common Multiple of 20,57,36,80,398

Least Common Multiple (LCM) of 20,57,36,80,398 is 2722320

2	20, 57, 36, 80, 398
2	10, 57, 18, 40, 199
3	5, 57, 9, 20, 199
5	5, 19, 3, 20, 199
	1, 19, 3, 4, 199

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 19 x 3 x 4 x 199 = 2722320

Least Common Multiple of 20,57,36,80,398 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 20,57,36,80,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,57,36,80,398) = 1

common factors(in case of two or more numbers have common factors) = 480

GCF(20,57,36,80,398) x common factors =1 x 480 = 480

LCM(20,57,36,80,398) = ( 20 × 57 × 36 × 80 × 398 ) / 480

LCM(20,57,36,80,398) = 1306713600 / 480

LCM(20,57,36,80,398) = 2722320

∴ Least Common Multiple of 20,57,36,80,398 is 2722320
