### More about the Number 1610:

1610 is the hypotenuse of a Pythagorean triple:

966-1288-1610, which is (3-4-**5**) times **322**.

1610 is not the sum of two squares or the difference of two squares. 1610 is a leg in some Pythagorean triples because

2(805)(1) = 1610,

2(161)(5) = 1610,

2(115)(7) = 1610, and

2(35)(23) = 1610.

You can calculate those Pythagorean triples by letting a be the first number in parenthesis for each of those equations, and b be the second number in parenthesis. Then substitute those values in the three expressions below, and you will have some Pythagorean triples!

2(a)(b), a² – b², a² + b².
