(a) What are the prime divisors of 100?

(b) What are the prime divisors of 144?

(a) $$100 = (2)^2(5)^2$$ so the prime divisors are 2 and 5. (b) $$144 = (2)^4 (3)^2$$ so the prime divisors are 2 and 3.

(a) $$100 = (2)(2)(5)(5)$$. So the PRIME divisors are 2 and 5.

(b) $$144 = (2)(2)(2)(2)(3)(3)$$. So the PRIME divisors are 2 and 3.
