Patterns that help you remember it
- The last digits repeat in a cycle of 5: 2, 4, 6, 8, 0.
- Every answer is even, because 1722 is even.
- Split it into tens and ones: 1722 × k = 1720 × k + 2 × k.
- Each answer is 1722 more than the one before, so you can count on in steps of 1722.
Building it from tables you already know
Every answer in the 1722 times table is double the answer in the 861 times table: 861 × 6 = 5,166, so 1722 × 6 = 10,332. To multiply 1722 by 9, multiply by 10 and take one 1722 away: 17,220 − 1722 = 15,498. To multiply by 11, multiply by 10 and add one more 1722: 17,220 + 1722 = 18,942. Multiplying by 4 is doubling twice: 1722 → 3,444 → 6,888.
Every multiple of 1722 is at least 1722, so there are none below 100 and 0 below 1,000. A number is in the 1722 times table exactly when it divides by 1722 with no remainder.
Odd, even and the last digit
Because 1722 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 1722 × 10 = 17,220, and 1722 × 100 = 172,200. Multiplying by 5 is half of multiplying by 10: half of 17,220 is 8,610.
Using the 1722 times table to divide
Every fact also works backwards: because 1722 × 7 = 12,054, you know 12,054 ÷ 1722 = 7 and 12,054 ÷ 7 = 1722. Practising the table and its division facts together halves the work.

What is half of 1722 × 8?
1722 × 8 = 13,776, and half of that is 6,888, which is 1722 × 4. Halving one factor halves the answer.
What is 1722 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1722 contain nothing.
What is 1722 × 7 and 1722 × 8?
1722 × 7 = 12,054 and 1722 × 8 = 13,776. These two are the facts most people find hardest, so they are worth practising on their own.
