Patterns that help you remember it
- The last digits repeat in a cycle of 5: 6, 2, 8, 4, 0.
- Every answer is even, because 1666 is even.
- Split it into tens and ones: 1666 × k = 1660 × k + 6 × k.
- Each answer is 1666 more than the one before, so you can count on in steps of 1666.
Building it from tables you already know
Every answer in the 1666 times table is double the answer in the 833 times table: 833 × 6 = 4,998, so 1666 × 6 = 9,996. To multiply 1666 by 9, multiply by 10 and take one 1666 away: 16,660 − 1666 = 14,994. To multiply by 11, multiply by 10 and add one more 1666: 16,660 + 1666 = 18,326. Multiplying by 4 is doubling twice: 1666 → 3,332 → 6,664.
Every multiple of 1666 is at least 1666, so there are none below 100 and 0 below 1,000. A number is in the 1666 times table exactly when it divides by 1666 with no remainder.
Odd, even and the last digit
Because 1666 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: 1666 × 10 = 16,660, and 1666 × 100 = 166,600. Multiplying by 5 is half of multiplying by 10: half of 16,660 is 8,330.
Using the 1666 times table to divide
Every fact also works backwards: because 1666 × 7 = 11,662, you know 11,662 ÷ 1666 = 7 and 11,662 ÷ 7 = 1666. Practising the table and its division facts together halves the work.

Answer
4 × 1666 = 6,664 pencils. - Tickets cost $1666 each. How much do 10 tickets cost?
Answer
10 × $1666 = $16,660. - 14,994 chairs are set out in rows of 1666. How many rows are there?

Questions
What is 1666 × 12?
19,992.
What is half of 1666 × 8?
1666 × 8 = 13,328, and half of that is 6,664, which is 1666 × 4. Halving one factor halves the answer.
What is 1666 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1666 contain nothing.
What is 1666 × 7 and 1666 × 8?
1666 × 7 = 11,662 and 1666 × 8 = 13,328. These two are the facts most people find hardest, so they are worth practising on their own.
Is 24,990 in the 1666 times table?
Yes: 24,990 ÷ 1666 = 15 with no remainder. 24,991 is not, because dividing it by 1666 leaves a remainder of 1.
How do I learn the 1666 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.
