Patterns that help you remember it
- The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
- The digits of every answer add up to a multiple of 9.
- Split it into tens and ones: 1791 × k = 1790 × k + 1 × k.
- Each answer is 1791 more than the one before, so you can count on in steps of 1791.
Building it from tables you already know
To multiply 1791 by 9, multiply by 10 and take one 1791 away: 17,910 − 1791 = 16,119. To multiply by 11, multiply by 10 and add one more 1791: 17,910 + 1791 = 19,701. Multiplying by 4 is doubling twice: 1791 → 3,582 → 7,164.
Every multiple of 1791 is at least 1791, so there are none below 100 and 0 below 1,000. A number is in the 1791 times table exactly when it divides by 1791 with no remainder.
Odd, even and the last digit
Because 1791 is odd, the answers alternate between odd and even: 1791 × 1 = 1791 is odd, 1791 × 2 = 3,582 is even, and so on. Multiplying by 10 always puts a zero on the end: 1791 × 10 = 17,910, and 1791 × 100 = 179,100. Multiplying by 5 is half of multiplying by 10: half of 17,910 is 8,955.
Using the 1791 times table to divide
Every fact also works backwards: because 1791 × 7 = 12,537, you know 12,537 ÷ 1791 = 7 and 12,537 ÷ 7 = 1791. Practising the table and its division facts together halves the work.

Questions
What is 1791 × 12?
21,492.
What is half of 1791 × 8?
1791 × 8 = 14,328, and half of that is 7,164, which is 1791 × 4. Halving one factor halves the answer.
What is 1791 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1791 contain nothing.
What is 1791 × 7 and 1791 × 8?
1791 × 7 = 12,537 and 1791 × 8 = 14,328. These two are the facts most people find hardest, so they are worth practising on their own.
Is 26,865 in the 1791 times table?
Yes: 26,865 ÷ 1791 = 15 with no remainder. 26,866 is not, because dividing it by 1791 leaves a remainder of 1.
How do I learn the 1791 times table quickly?
Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
