The triangle with sides 3, 4, and 5, is the smallest integer sided pythagorean triangle. Can you prove that in every such triangle:
- at least one of its sides must be multiple of 3?
- at least one of its sides must be multiple of 4?
- at least one of its sides must be multiple of 5?
no, because 3 4 5 is relative to the proportion of the sides to each other and not to divisibility by those particular numbers...
