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 438 is even.
- Split it into tens and ones: 438 × k = 430 × k + 8 × k.
- Each answer is 438 more than the one before, so you can count on in steps of 438.
Building it from tables you already know
Every answer in the 438 times table is double the answer in the 219 times table: 219 × 6 = 1,314, so 438 × 6 = 2,628. To multiply 438 by 9, multiply by 10 and take one 438 away: 4,380 − 438 = 3,942. To multiply by 11, multiply by 10 and add one more 438: 4,380 + 438 = 4,818. Multiplying by 4 is doubling twice: 438 → 876 → 1,752.
Every multiple of 438 is at least 438, so there are none below 100 and 2 below 1,000. A number is in the 438 times table exactly when it divides by 438 with no remainder.
Odd, even and the last digit
Because 438 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: 438 × 10 = 4,380, and 438 × 100 = 43,800. Multiplying by 5 is half of multiplying by 10: half of 4,380 is 2,190.
Using the 438 times table to divide
Every fact also works backwards: because 438 × 7 = 3,066, you know 3,066 ÷ 438 = 7 and 3,066 ÷ 7 = 438. 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:
- A box holds 438 pencils. How many pencils are in 7 boxes?
Answer
7 × 438 = 3,066 pencils. - Tickets cost $438 each. How much do 8 tickets cost?
Answer
8 × $438 = $3,504. - 1,314 chairs are set out in rows of 438. How many rows are there?
Answer
1,314 ÷ 438 = 3 rows. - A plant grows 438 millimetres a week. How much does it grow in 12 weeks?

12 × 438 = 5,256 millimetres.
Questions
What is 438 × 12?
5,256.
What is half of 438 × 8?
438 × 8 = 3,504, and half of that is 1,752, which is 438 × 4. Halving one factor halves the answer.
What is 438 times 0?
0. Any number multiplied by zero is zero, because zero groups of 438 contain nothing.
What is 438 × 7 and 438 × 8?
438 × 7 = 3,066 and 438 × 8 = 3,504. These two are the facts most people find hardest, so they are worth practising on their own.
Is 6,570 in the 438 times table?
Yes: 6,570 ÷ 438 = 15 with no remainder. 6,571 is not, because dividing it by 438 leaves a remainder of 1.
How do I learn the 438 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.
