Patterns that help you remember it
- The last digits repeat in a cycle of 5: 8, 6, 4, 2, 0.
- Every answer is even, because 1788 is even.
- Split it into tens and ones: 1788 × k = 1780 × k + 8 × k.
- Each answer is 1788 more than the one before, so you can count on in steps of 1788.
Building it from tables you already know
Every answer in the 1788 times table is double the answer in the 894 times table: 894 × 6 = 5,364, so 1788 × 6 = 10,728. To multiply 1788 by 9, multiply by 10 and take one 1788 away: 17,880 − 1788 = 16,092. To multiply by 11, multiply by 10 and add one more 1788: 17,880 + 1788 = 19,668. Multiplying by 4 is doubling twice: 1788 → 3,576 → 7,152.
Every multiple of 1788 is at least 1788, so there are none below 100 and 0 below 1,000. A number is in the 1788 times table exactly when it divides by 1788 with no remainder.
Odd, even and the last digit
Because 1788 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: 1788 × 10 = 17,880, and 1788 × 100 = 178,800. Multiplying by 5 is half of multiplying by 10: half of 17,880 is 8,940.
Using the 1788 times table to divide
Every fact also works backwards: because 1788 × 7 = 12,516, you know 12,516 ÷ 1788 = 7 and 12,516 ÷ 7 = 1788. Practising the table and its division facts together halves the work.

21,456.
What is half of 1788 × 8?
1788 × 8 = 14,304, and half of that is 7,152, which is 1788 × 4. Halving one factor halves the answer.
What is 1788 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1788 contain nothing.
What is 1788 × 7 and 1788 × 8?
1788 × 7 = 12,516 and 1788 × 8 = 14,304. These two are the facts most people find hardest, so they are worth practising on their own.
