Can anyone tell me the proof of Primitive Pythagorean Triples(a,b,c) having gcd(a,b,c)=1

I was solving this question Pythagorean Theorem II

and saw some optimized solution based on this relation seems

Saw some solved optimized codes using this relations seems gcd(a,b,c)=1

I know a,b,c are relatively prime but is it enough to know that ?

Can somebody tell me proof of this approach ?
