Patterns that help you remember it
- The last digits repeat in a cycle of 5: 8, 6, 4, 2, 0.
- Every answer is even, because 1668 is even.
- Split it into tens and ones: 1668 × k = 1660 × k + 8 × k.
- Each answer is 1668 more than the one before, so you can count on in steps of 1668.
Building it from tables you already know
Every answer in the 1668 times table is double the answer in the 834 times table: 834 × 6 = 5,004, so 1668 × 6 = 10,008. To multiply 1668 by 9, multiply by 10 and take one 1668 away: 16,680 − 1668 = 15,012. To multiply by 11, multiply by 10 and add one more 1668: 16,680 + 1668 = 18,348. Multiplying by 4 is doubling twice: 1668 → 3,336 → 6,672.
Every multiple of 1668 is at least 1668, so there are none below 100 and 0 below 1,000. A number is in the 1668 times table exactly when it divides by 1668 with no remainder.
Odd, even and the last digit
Because 1668 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: 1668 × 10 = 16,680, and 1668 × 100 = 166,800. Multiplying by 5 is half of multiplying by 10: half of 16,680 is 8,340.
Using the 1668 times table to divide
Every fact also works backwards: because 1668 × 7 = 11,676, you know 11,676 ÷ 1668 = 7 and 11,676 ÷ 7 = 1668. Practising the table and its division facts together halves the work.

Questions
What is 1668 × 12?
20,016.
What is half of 1668 × 8?
1668 × 8 = 13,344, and half of that is 6,672, which is 1668 × 4. Halving one factor halves the answer.
What is 1668 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1668 contain nothing.
What is 1668 × 7 and 1668 × 8?
1668 × 7 = 11,676 and 1668 × 8 = 13,344. These two are the facts most people find hardest, so they are worth practising on their own.
Is 25,020 in the 1668 times table?
Yes: 25,020 ÷ 1668 = 15 with no remainder. 25,021 is not, because dividing it by 1668 leaves a remainder of 1.
How do I learn the 1668 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.
