172 (one hundred [and] seventy-two) is thenatural number following171 and preceding173.

In mathematics

[edit]

172 is a part of a near-miss for being a counterexample toFermat's Last Theorem, as 1353 + 1383 = 1723 − 1. This is only the third near-miss of this form, two cubes adding to one less than a third cube.[1] It is also a "thickened cube number", half an odd cube (73 = 343) rounded up to the next integer.[2]
