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.
221, 442, 663, 884 and so on.
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.
Apart from itself and 1, the only numbers that divide evenly into 221 are 13 and 17. Therefore, 221 = 13 x 17.
13 x 17 = 221
221
13 times 17 = 221
There are no two primes whose sum is 221.
13 x 17 = 221
It is their lowest common multiple which is 221 13 and 17 are both prime numbers
