Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 1690 is even.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 1690 × k = 1690 × k + 0 × k.
- Each answer is 1690 more than the one before, so you can count on in steps of 1690.
Building it from tables you already know
Every answer in the 1690 times table is double the answer in the 845 times table: 845 × 6 = 5,070, so 1690 × 6 = 10,140. To multiply 1690 by 9, multiply by 10 and take one 1690 away: 16,900 − 1690 = 15,210. To multiply by 11, multiply by 10 and add one more 1690: 16,900 + 1690 = 18,590. Multiplying by 4 is doubling twice: 1690 → 3,380 → 6,760.
Every multiple of 1690 is at least 1690, so there are none below 100 and 0 below 1,000. A number is in the 1690 times table exactly when it divides by 1690 with no remainder.
Odd, even and the last digit
Because 1690 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: 1690 × 10 = 16,900, and 1690 × 100 = 169,000. Multiplying by 5 is half of multiplying by 10: half of 16,900 is 8,450.
Using the 1690 times table to divide
Every fact also works backwards: because 1690 × 7 = 11,830, you know 11,830 ÷ 1690 = 7 and 11,830 ÷ 7 = 1690. 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 1690 pencils. How many pencils are in 9 boxes?
Answer
9 × 1690 = 15,210 pencils. - Tickets cost $1690 each. How much do 5 tickets cost?
Answer
5 × $1690 = $8,450. - 15,210 chairs are set out in rows of 1690. How many rows are there?
Answer
15,210 ÷ 1690 = 9 rows. - A plant grows 1690 millimetres a week. How much does it grow in 6 weeks?
Answer
6 × 1690 = 10,140 millimetres.
Questions
What is 1690 × 12?
20,280.
What is half of 1690 × 8?
1690 × 8 = 13,520, and half of that is 6,760, which is 1690 × 4. Halving one factor halves the answer.
What is 1690 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1690 contain nothing.
What is 1690 × 7 and 1690 × 8?
1690 × 7 = 11,830 and 1690 × 8 = 13,520. These two are the facts most people find hardest, so they are worth practising on their own.
Is 25,350 in the 1690 times table?
Yes: 25,350 ÷ 1690 = 15 with no remainder. 25,351 is not, because dividing it by 1690 leaves a remainder of 1.
How do I learn the 1690 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.
