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 138 is even.
  • Split it into tens and ones: 138 × k = 130 × k + 8 × k.
  • Each answer is 138 more than the one before, so you can count on in steps of 138.

Building it from tables you already know

Every answer in the 138 times table is double the answer in the 69 times table: 69 × 6 = 414, so 138 × 6 = 828. To multiply 138 by 9, multiply by 10 and take one 138 away: 1,380 − 138 = 1,242. To multiply by 11, multiply by 10 and add one more 138: 1,380 + 138 = 1,518. Multiplying by 4 is doubling twice: 138 → 276 → 552.

Every multiple of 138 is at least 138, so there are none below 100 and 7 below 1,000. A number is in the 138 times table exactly when it divides by 138 with no remainder.

Odd, even and the last digit

Because 138 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: 138 × 10 = 1,380, and 138 × 100 = 13,800. Multiplying by 5 is half of multiplying by 10: half of 1,380 is 690.

Using the 138 times table to divide

Every fact also works backwards: because 138 × 7 = 966, you know 966 ÷ 138 = 7 and 966 ÷ 7 = 138. Practising the table and its division facts together halves the work.

Questions

What is 138 × 12?

1,656.

What is half of 138 × 8?

138 × 8 = 1,104, and half of that is 552, which is 138 × 4. Halving one factor halves the answer.

What is 138 times 0?

0. Any number multiplied by zero is zero, because zero groups of 138 contain nothing.

What is 138 × 7 and 138 × 8?

138 × 7 = 966 and 138 × 8 = 1,104. These two are the facts most people find hardest, so they are worth practising on their own.
