13 and 17: 221 = 13 x 17
The prime factors of 221 are 13 and 17. They're the only prime numbers that will divide evenly into 221 with no remainder.
13 times 17 = 221

13 x 17 = 221
To determine what goes into 221, we can look at its factors. The numbers that multiply together to give 221 are 1, 13, 17, and 221 itself. Specifically, 221 can be expressed as the product of 13 and 17 (13 × 17 = 221). Thus, the factors of 221 include both prime numbers and 1.
221 is prime so nothing but 1 and 221 go into 221. 32 is 25 so 1, 2, 4, 8, 16 and 32 go into 32. The numbers are coprime, so only 1 goes into both.
