I would try the lower primes to check first, and here the first to try should be 3. Why? 2%2B0%2B1%2B3=6, which is a rule showing that 2013 is a product of 3.

2013%2F3=671

My way is probably very crude, but I took another fairly small prime, 11, and just divided: 671%2F11=61

61 is a prime number, and is largest of the three found.

2013=3%2A11%2A61

Look for factors less than sqrt(2013) <= 44
