Least Common Multiple of 820,8400

Least Common Multiple (LCM) of 820,8400 is 344400

2	820, 8400
2	410, 4200
5	205, 2100
	41, 420

∴ So the LCM of the given numbers is 2 x 2 x 5 x 41 x 420 = 344400

Least Common Multiple of 820,8400 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 820,8400 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(820,8400) = 20

common factors(in case of two or more numbers have common factors) = 1

GCF(820,8400) x common factors =20 x 1 = 20

LCM(820,8400) = ( 820 × 8400 ) / 20

LCM(820,8400) = 6888000 / 20

LCM(820,8400) = 344400

∴ Least Common Multiple of 820,8400 is 344400
