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 1238 is even.
- Split it into tens and ones: 1238 × k = 1230 × k + 8 × k.
- Each answer is 1238 more than the one before, so you can count on in steps of 1238.
Building it from tables you already know
Every answer in the 1238 times table is double the answer in the 619 times table: 619 × 6 = 3,714, so 1238 × 6 = 7,428. To multiply 1238 by 9, multiply by 10 and take one 1238 away: 12,380 − 1238 = 11,142. To multiply by 11, multiply by 10 and add one more 1238: 12,380 + 1238 = 13,618. Multiplying by 4 is doubling twice: 1238 → 2,476 → 4,952.
Every multiple of 1238 is at least 1238, so there are none below 100 and 0 below 1,000. A number is in the 1238 times table exactly when it divides by 1238 with no remainder.
Odd, even and the last digit
Because 1238 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: 1238 × 10 = 12,380, and 1238 × 100 = 123,800. Multiplying by 5 is half of multiplying by 10: half of 12,380 is 6,190.
Using the 1238 times table to divide
Every fact also works backwards: because 1238 × 7 = 8,666, you know 8,666 ÷ 1238 = 7 and 8,666 ÷ 7 = 1238. 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:

Answer
7 × 1238 = 8,666 pencils. - Tickets cost $1238 each. How much do 11 tickets cost?
Answer
11 × $1238 = $13,618. - 3,714 chairs are set out in rows of 1238. How many rows are there?
Answer
3,714 ÷ 1238 = 3 rows. - A plant grows 1238 millimetres a week. How much does it grow in 8 weeks?
Answer

Questions
What is 1238 × 12?
14,856.
What is half of 1238 × 8?
1238 × 8 = 9,904, and half of that is 4,952, which is 1238 × 4. Halving one factor halves the answer.
What is 1238 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1238 contain nothing.
What is 1238 × 7 and 1238 × 8?
1238 × 7 = 8,666 and 1238 × 8 = 9,904. These two are the facts most people find hardest, so they are worth practising on their own.
Is 18,570 in the 1238 times table?
Yes: 18,570 ÷ 1238 = 15 with no remainder. 18,571 is not, because dividing it by 1238 leaves a remainder of 1.
How do I learn the 1238 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.
