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 1438 is even.
- Split it into tens and ones: 1438 × k = 1430 × k + 8 × k.
- Each answer is 1438 more than the one before, so you can count on in steps of 1438.
Building it from tables you already know
Every answer in the 1438 times table is double the answer in the 719 times table: 719 × 6 = 4,314, so 1438 × 6 = 8,628. To multiply 1438 by 9, multiply by 10 and take one 1438 away: 14,380 − 1438 = 12,942. To multiply by 11, multiply by 10 and add one more 1438: 14,380 + 1438 = 15,818. Multiplying by 4 is doubling twice: 1438 → 2,876 → 5,752.
Every multiple of 1438 is at least 1438, so there are none below 100 and 0 below 1,000. A number is in the 1438 times table exactly when it divides by 1438 with no remainder.
Odd, even and the last digit
Because 1438 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: 1438 × 10 = 14,380, and 1438 × 100 = 143,800. Multiplying by 5 is half of multiplying by 10: half of 14,380 is 7,190.
Using the 1438 times table to divide
Every fact also works backwards: because 1438 × 7 = 10,066, you know 10,066 ÷ 1438 = 7 and 10,066 ÷ 7 = 1438. Practising the table and its division facts together halves the work.

17,256.
What is half of 1438 × 8?
1438 × 8 = 11,504, and half of that is 5,752, which is 1438 × 4. Halving one factor halves the answer.
What is 1438 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1438 contain nothing.
What is 1438 × 7 and 1438 × 8?
1438 × 7 = 10,066 and 1438 × 8 = 11,504. These two are the facts most people find hardest, so they are worth practising on their own.
Is 21,570 in the 1438 times table?
Yes: 21,570 ÷ 1438 = 15 with no remainder. 21,571 is not, because dividing it by 1438 leaves a remainder of 1.
How do I learn the 1438 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.
