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 1808 is even.
- Split it into tens and ones: 1808 × k = 1800 × k + 8 × k.
- Each answer is 1808 more than the one before, so you can count on in steps of 1808.
Building it from tables you already know
Every answer in the 1808 times table is double the answer in the 904 times table: 904 × 6 = 5,424, so 1808 × 6 = 10,848. To multiply 1808 by 9, multiply by 10 and take one 1808 away: 18,080 − 1808 = 16,272. To multiply by 11, multiply by 10 and add one more 1808: 18,080 + 1808 = 19,888. Multiplying by 4 is doubling twice: 1808 → 3,616 → 7,232.
Every multiple of 1808 is at least 1808, so there are none below 100 and 0 below 1,000. A number is in the 1808 times table exactly when it divides by 1808 with no remainder.
Odd, even and the last digit
Because 1808 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: 1808 × 10 = 18,080, and 1808 × 100 = 180,800. Multiplying by 5 is half of multiplying by 10: half of 18,080 is 9,040.
Using the 1808 times table to divide
Every fact also works backwards: because 1808 × 7 = 12,656, you know 12,656 ÷ 1808 = 7 and 12,656 ÷ 7 = 1808. Practising the table and its division facts together halves the work.

Word problems
Times tables are most useful when you can spot them in a question. Try these, then open each one to check:
- A box holds 1808 pencils. How many pencils are in 3 boxes?
Answer
3 × 1808 = 5,424 pencils. - Tickets cost $1808 each. How much do 5 tickets cost?
Answer
5 × $1808 = $9,040. - 14,464 chairs are set out in rows of 1808. How many rows are there?
Answer
14,464 ÷ 1808 = 8 rows. - A plant grows 1808 millimetres a week. How much does it grow in 11 weeks?
Answer
11 × 1808 = 19,888 millimetres.
Questions
What is 1808 × 12?
21,696.
What is half of 1808 × 8?
1808 × 8 = 14,464, and half of that is 7,232, which is 1808 × 4. Halving one factor halves the answer.
What is 1808 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1808 contain nothing.
What is 1808 × 7 and 1808 × 8?
1808 × 7 = 12,656 and 1808 × 8 = 14,464. These two are the facts most people find hardest, so they are worth practising on their own.
Is 27,120 in the 1808 times table?
Yes: 27,120 ÷ 1808 = 15 with no remainder. 27,121 is not, because dividing it by 1808 leaves a remainder of 1.
How do I learn the 1808 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.
