Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 1830 is even.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 1830 × k = 1830 × k + 0 × k.
- Each answer is 1830 more than the one before, so you can count on in steps of 1830.
Building it from tables you already know
Every answer in the 1830 times table is double the answer in the 915 times table: 915 × 6 = 5,490, so 1830 × 6 = 10,980. To multiply 1830 by 9, multiply by 10 and take one 1830 away: 18,300 − 1830 = 16,470. To multiply by 11, multiply by 10 and add one more 1830: 18,300 + 1830 = 20,130. Multiplying by 4 is doubling twice: 1830 → 3,660 → 7,320.
Every multiple of 1830 is at least 1830, so there are none below 100 and 0 below 1,000. A number is in the 1830 times table exactly when it divides by 1830 with no remainder.
Odd, even and the last digit
Because 1830 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: 1830 × 10 = 18,300, and 1830 × 100 = 183,000. Multiplying by 5 is half of multiplying by 10: half of 18,300 is 9,150.
Using the 1830 times table to divide
Every fact also works backwards: because 1830 × 7 = 12,810, you know 12,810 ÷ 1830 = 7 and 12,810 ÷ 7 = 1830. 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 1830 pencils. How many pencils are in 8 boxes?
Answer
8 × 1830 = 14,640 pencils. - Tickets cost $1830 each. How much do 8 tickets cost?
Answer
8 × $1830 = $14,640. - 10,980 chairs are set out in rows of 1830. How many rows are there?
Answer
10,980 ÷ 1830 = 6 rows. - A plant grows 1830 millimetres a week. How much does it grow in 12 weeks?
Answer
12 × 1830 = 21,960 millimetres.
Questions
What is 1830 × 12?
21,960.
What is half of 1830 × 8?
1830 × 8 = 14,640, and half of that is 7,320, which is 1830 × 4. Halving one factor halves the answer.
What is 1830 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1830 contain nothing.
What is 1830 × 7 and 1830 × 8?
1830 × 7 = 12,810 and 1830 × 8 = 14,640. These two are the facts most people find hardest, so they are worth practising on their own.
Is 27,450 in the 1830 times table?
Yes: 27,450 ÷ 1830 = 15 with no remainder. 27,451 is not, because dividing it by 1830 leaves a remainder of 1.
How do I learn the 1830 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.
