Patterns that help you remember it
- The last digits repeat in a cycle of 10: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.
- Split it into tens and ones: 1789 × k = 1780 × k + 9 × k.
- Each answer is 1789 more than the one before, so you can count on in steps of 1789.
Building it from tables you already know
To multiply 1789 by 9, multiply by 10 and take one 1789 away: 17,890 − 1789 = 16,101. To multiply by 11, multiply by 10 and add one more 1789: 17,890 + 1789 = 19,679. Multiplying by 4 is doubling twice: 1789 → 3,578 → 7,156.
Every multiple of 1789 is at least 1789, so there are none below 100 and 0 below 1,000. A number is in the 1789 times table exactly when it divides by 1789 with no remainder.
Odd, even and the last digit
Because 1789 is odd, the answers alternate between odd and even: 1789 × 1 = 1789 is odd, 1789 × 2 = 3,578 is even, and so on. Multiplying by 10 always puts a zero on the end: 1789 × 10 = 17,890, and 1789 × 100 = 178,900. Multiplying by 5 is half of multiplying by 10: half of 17,890 is 8,945.
Using the 1789 times table to divide
Every fact also works backwards: because 1789 × 7 = 12,523, you know 12,523 ÷ 1789 = 7 and 12,523 ÷ 7 = 1789. Practising the table and its division facts together halves the work.

21,468.
What is half of 1789 × 8?
1789 × 8 = 14,312, and half of that is 7,156, which is 1789 × 4. Halving one factor halves the answer.
What is 1789 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1789 contain nothing.
What is 1789 × 7 and 1789 × 8?
1789 × 7 = 12,523 and 1789 × 8 = 14,312. These two are the facts most people find hardest, so they are worth practising on their own.
Is 26,835 in the 1789 times table?
Yes: 26,835 ÷ 1789 = 15 with no remainder. 26,836 is not, because dividing it by 1789 leaves a remainder of 1.
How do I learn the 1789 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.
