(a) What is the prime factorization of 372?
372 = (2)(186)
= (2)(2)(93)
= (2)(2)(3)(31)

-------------------------------------

(b) What are the positive divisors of 372?
List in pairs, starting with the smallest and largest divisors, and work towards the middle....
{1, 372}
{1, 2, 186, 372}
{1, 2, 3, 124, 186, 372}
{1, 2, 3, 4, 93, 124, 186, 372}
{1, 2, 3, 4, 6, 62, 93, 124, 186, 372}
{1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372}
