Question 722997
List the numbers out from 62 to 72
{62,63,64,65,66,67,68,69,70,71,72}
It needs to be a composite # so take those primes out!
{62,63,64,65,66,68,69,70,72}
Now find a prime in the sum of the numbers
6+2=8 NOPE 
6+3=9 NOPE
6+4=10 NOPE
6+5=11 YEP!
6+6=12 NOPE
6+8=14 NOPE
6+9=15 NOPE
7+0=7 YEP!
7+2=9 NOPE

So now down to the last two numbers
{65&70}
finally find the # with MORE than 4 factors. Very key to see that it wants more than four. 

65-> 1, 5, 13, 65 This has only four so it can't be it since we need more than four.

70-> 1, 2, 5, 7, 10, 14, 35, 70 This has WAY more than four for sure, it has eight so this by default and with reason is the right answer. 

Answer: 70

Make sure to go through the whole thing sometimes even the smallest mistake can get the best of us. Hope this helped
