Patterns that help you remember it
- The last digits repeat in a cycle of 5: 4, 8, 2, 6, 0.
- Every answer is even, because 1804 is even.
- Split it into tens and ones: 1804 × k = 1800 × k + 4 × k.
- Each answer is 1804 more than the one before, so you can count on in steps of 1804.
Building it from tables you already know
Every answer in the 1804 times table is double the answer in the 902 times table: 902 × 6 = 5,412, so 1804 × 6 = 10,824. To multiply 1804 by 9, multiply by 10 and take one 1804 away: 18,040 − 1804 = 16,236. To multiply by 11, multiply by 10 and add one more 1804: 18,040 + 1804 = 19,844. Multiplying by 4 is doubling twice: 1804 → 3,608 → 7,216.
Every multiple of 1804 is at least 1804, so there are none below 100 and 0 below 1,000. A number is in the 1804 times table exactly when it divides by 1804 with no remainder.
Odd, even and the last digit
Because 1804 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: 1804 × 10 = 18,040, and 1804 × 100 = 180,400. Multiplying by 5 is half of multiplying by 10: half of 18,040 is 9,020.
Using the 1804 times table to divide
Every fact also works backwards: because 1804 × 7 = 12,628, you know 12,628 ÷ 1804 = 7 and 12,628 ÷ 7 = 1804. 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:

Answer
3 × 1804 = 5,412 pencils. - Tickets cost $1804 each. How much do 6 tickets cost?
Answer
6 × $1804 = $10,824. - 12,628 chairs are set out in rows of 1804. How many rows are there?
Answer
12,628 ÷ 1804 = 7 rows. - A plant grows 1804 millimetres a week. How much does it grow in 6 weeks?

Questions
What is 1804 × 12?
21,648.
What is half of 1804 × 8?
1804 × 8 = 14,432, and half of that is 7,216, which is 1804 × 4. Halving one factor halves the answer.
What is 1804 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1804 contain nothing.
What is 1804 × 7 and 1804 × 8?
1804 × 7 = 12,628 and 1804 × 8 = 14,432. These two are the facts most people find hardest, so they are worth practising on their own.
Is 27,060 in the 1804 times table?
Yes: 27,060 ÷ 1804 = 15 with no remainder. 27,061 is not, because dividing it by 1804 leaves a remainder of 1.
How do I learn the 1804 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.
