Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 1790 is even.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 1790 × k = 1790 × k + 0 × k.
- Each answer is 1790 more than the one before, so you can count on in steps of 1790.
Building it from tables you already know
Every answer in the 1790 times table is double the answer in the 895 times table: 895 × 6 = 5,370, so 1790 × 6 = 10,740. To multiply 1790 by 9, multiply by 10 and take one 1790 away: 17,900 − 1790 = 16,110. To multiply by 11, multiply by 10 and add one more 1790: 17,900 + 1790 = 19,690. Multiplying by 4 is doubling twice: 1790 → 3,580 → 7,160.
Every multiple of 1790 is at least 1790, so there are none below 100 and 0 below 1,000. A number is in the 1790 times table exactly when it divides by 1790 with no remainder.
Odd, even and the last digit
Because 1790 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: 1790 × 10 = 17,900, and 1790 × 100 = 179,000. Multiplying by 5 is half of multiplying by 10: half of 17,900 is 8,950.
Using the 1790 times table to divide
Every fact also works backwards: because 1790 × 7 = 12,530, you know 12,530 ÷ 1790 = 7 and 12,530 ÷ 7 = 1790. 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
4 × 1790 = 7,160 pencils. - Tickets cost $1790 each. How much do 8 tickets cost?
Answer
8 × $1790 = $14,320. - 7,160 chairs are set out in rows of 1790. How many rows are there?
Answer
7,160 ÷ 1790 = 4 rows. - A plant grows 1790 millimetres a week. How much does it grow in 9 weeks?

9 × 1790 = 16,110 millimetres.
Questions
What is 1790 × 12?
21,480.
What is half of 1790 × 8?
1790 × 8 = 14,320, and half of that is 7,160, which is 1790 × 4. Halving one factor halves the answer.
What is 1790 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1790 contain nothing.
What is 1790 × 7 and 1790 × 8?
1790 × 7 = 12,530 and 1790 × 8 = 14,320. These two are the facts most people find hardest, so they are worth practising on their own.
Is 26,850 in the 1790 times table?
Yes: 26,850 ÷ 1790 = 15 with no remainder. 26,851 is not, because dividing it by 1790 leaves a remainder of 1.
How do I learn the 1790 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.
