2021 = 43*47

WLOG, let a >=b>=c.

[a][b][c] must be an integer, so we can set it equal to either 43 or 47

Since [a][b][c] is (usually) smaller than abc, let's set it to 43.

Since 43 is prime, [a] must be equal to 43, while [b] and [c] must both equal 1.

Also, keep in mind that abc has to multiply to 47.

One pretty obvious way for this system of equations to work is to set a equal to 43, set b equal to 47/43, and c equal to 1.

So one solution would be (43, 47/43, 1)
