Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Split it into tens and ones: 1001 × k = 1000 × k + 1 × k.
  • Each answer is 1001 more than the one before, so you can count on in steps of 1001.

Building it from tables you already know

To multiply 1001 by 9, multiply by 10 and take one 1001 away: 10,010 − 1001 = 9,009. To multiply by 11, multiply by 10 and add one more 1001: 10,010 + 1001 = 11,011. Multiplying by 4 is doubling twice: 1001 → 2,002 → 4,004.

Every multiple of 1001 is at least 1001, so there are none below 100 and 0 below 1,000. A number is in the 1001 times table exactly when it divides by 1001 with no remainder.

Odd, even and the last digit

Because 1001 is odd, the answers alternate between odd and even: 1001 × 1 = 1001 is odd, 1001 × 2 = 2,002 is even, and so on. Multiplying by 10 always puts a zero on the end: 1001 × 10 = 10,010, and 1001 × 100 = 100,100. Multiplying by 5 is half of multiplying by 10: half of 10,010 is 5,005.

Using the 1001 times table to divide

Every fact also works backwards: because 1001 × 7 = 7,007, you know 7,007 ÷ 1001 = 7 and 7,007 ÷ 7 = 1001. 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:

  1. A box holds 1001 pencils. How many pencils are in 4 boxes?
    Answer4 × 1001 = 4,004 pencils.
  2. Tickets cost $1001 each. How much do 11 tickets cost?
    Answer11 × $1001 = $11,011.
  3. 6,006 chairs are set out in rows of 1001. How many rows are there?
    Answer6,006 ÷ 1001 = 6 rows.
  4. A plant grows 1001 millimetres a week. How much does it grow in 12 weeks?
    Answer12 × 1001 = 12,012 millimetres.

Questions

What is 1001 × 12?

12,012.

What is half of 1001 × 8?

1001 × 8 = 8,008, and half of that is 4,004, which is 1001 × 4. Halving one factor halves the answer.

What is 1001 times 0?

0. Any number multiplied by zero is zero, because zero groups of 1001 contain nothing.

What is 1001 × 7 and 1001 × 8?

1001 × 7 = 7,007 and 1001 × 8 = 8,008. These two are the facts most people find hardest, so they are worth practising on their own.

Is 15,015 in the 1001 times table?

Yes: 15,015 ÷ 1001 = 15 with no remainder. 15,016 is not, because dividing it by 1001 leaves a remainder of 1.

How do I learn the 1001 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.
