The number 13 is a prime number because it only has 1 and 13 as factors and 13 is a odd number because it cannot be divided equally. 132 is 169 because 13 X 13 = 169. Another cool fact I found out is that 13 is a Fibonacci number, you generate Fibonacci numbers by adding together the two previous numbers in the sequence
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13

The first 10 multiples of 13 are 13, 26, 39, 52, 65, 88, 91, 104, 117, and 130. 13 is a deficient number because 13's factors are 1 and 13 and a deficient number is a numbers whose factors are less than the number (not counting itself).
