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: 381 × k = 380 × k + 1 × k.
  • Each answer is 381 more than the one before, so you can count on in steps of 381.

Building it from tables you already know

To multiply 381 by 9, multiply by 10 and take one 381 away: 3,810 − 381 = 3,429. To multiply by 11, multiply by 10 and add one more 381: 3,810 + 381 = 4,191. Multiplying by 4 is doubling twice: 381 → 762 → 1,524.

Every multiple of 381 is at least 381, so there are none below 100 and 2 below 1,000. A number is in the 381 times table exactly when it divides by 381 with no remainder.

Odd, even and the last digit

Because 381 is odd, the answers alternate between odd and even: 381 × 1 = 381 is odd, 381 × 2 = 762 is even, and so on. Multiplying by 10 always puts a zero on the end: 381 × 10 = 3,810, and 381 × 100 = 38,100. Multiplying by 5 is half of multiplying by 10: half of 3,810 is 1,905.

Using the 381 times table to divide

Every fact also works backwards: because 381 × 7 = 2,667, you know 2,667 ÷ 381 = 7 and 2,667 ÷ 7 = 381. Practising the table and its division facts together halves the work.

Questions

What is 381 × 12?

4,572.

What is half of 381 × 8?

381 × 8 = 3,048, and half of that is 1,524, which is 381 × 4. Halving one factor halves the answer.

What is 381 times 0?

0. Any number multiplied by zero is zero, because zero groups of 381 contain nothing.

What is 381 × 7 and 381 × 8?

381 × 7 = 2,667 and 381 × 8 = 3,048. These two are the facts most people find hardest, so they are worth practising on their own.
