The way to find prime factors is to make a "tree" to represent prime factors. For example for fifty, it's 50=2*25=5*5, so the prime numbers are two and five. For sixty, just make another tree. 60=3*30=5*6=3*2. So the answers are two, three and five.
Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)
