How do you determine if a set of numbers form a Pythagorean triple?

The 3 numbers must be multiples of 3, 4, and 5

Step-by-step explanation:

Pythagorean Triples are numbers that you know will come out perfectly in the Pythagorean Theorem. But the easiest way to explain this is to show you an example.

Say you're given the numbers 12, 16, and 20.

They should be able to be divided by the same number and equal 3, 4, and 5.

In this case, the number is 4.

12/4=3

16/4=4

20/4=5

So, this is a 3-4-5 triangle, or a Pythagorean Triple.

Since a Pythagorean triple is three positive integers a, b, and c such that (a^2) + (b^2) = (c^2), first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25.
