Answer:

Step-by-step explanation:

4 and 9 are composite numbers, so that automatically rules them out. The last two Prime numbers are 7 & 5, right?

180/7 = 25.71 - Since this ends up being a decimal, it cannot be a factor.

180/5 = 36

5 is both a prime number, and it factors evenly: this makes 5 the correct answer.

Hope I could help!
