Let's calculate the remainders for each division:

1. 13 divided by 1722
   The remainder is the result of $13 \mod 1722$.
   Since 13 is smaller than 1722, the remainder is 13.

2. 44 divided by 4896
   The remainder is the result of $44 \mod 4896$.
   Since 44 is smaller than 4896, the remainder is 44.

3. 65 divided by 99521
   The remainder is the result of $65 \mod 99521$.
   Since 65 is smaller than 99521, the remainder is 65.

So, the remainders are:

• 13
• 44
• 65
