835 is the hypotenuse of a Pythagorean triple, 501-668-835, which is **167** times (3-4-**5**).

835 can be written as the difference of two squares two different ways:

- 418² – 417² = 835
- 86² – 81² = 835

835 can be written as the sum of consecutive numbers three different ways.

- 417 + 418 = 835; that’s two consecutive numbers.
- 165 + 166 +
**167**+ 168 + 169 = 835; that’s**five**consecutive numbers. - 79 + 80 + 81 + 82 + 83 + 84 + 85 + 86 + 87 + 88 = 835; that’s ten consecutive numbers.
