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 1428 is even.
- Split it into tens and ones: 1428 × k = 1420 × k + 8 × k.
- Each answer is 1428 more than the one before, so you can count on in steps of 1428.
Building it from tables you already know
Every answer in the 1428 times table is double the answer in the 714 times table: 714 × 6 = 4,284, so 1428 × 6 = 8,568. To multiply 1428 by 9, multiply by 10 and take one 1428 away: 14,280 − 1428 = 12,852. To multiply by 11, multiply by 10 and add one more 1428: 14,280 + 1428 = 15,708. Multiplying by 4 is doubling twice: 1428 → 2,856 → 5,712.
Every multiple of 1428 is at least 1428, so there are none below 100 and 0 below 1,000. A number is in the 1428 times table exactly when it divides by 1428 with no remainder.
Odd, even and the last digit
Because 1428 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: 1428 × 10 = 14,280, and 1428 × 100 = 142,800. Multiplying by 5 is half of multiplying by 10: half of 14,280 is 7,140.
Using the 1428 times table to divide
Every fact also works backwards: because 1428 × 7 = 9,996, you know 9,996 ÷ 1428 = 7 and 9,996 ÷ 7 = 1428. 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 1428 pencils. How many pencils are in 4 boxes?
Answer
4 × 1428 = 5,712 pencils. - Tickets cost $1428 each. How much do 5 tickets cost?
Answer
5 × $1428 = $7,140. - 5,712 chairs are set out in rows of 1428. How many rows are there?
Answer
5,712 ÷ 1428 = 4 rows. - A plant grows 1428 millimetres a week. How much does it grow in 8 weeks?
Answer
8 × 1428 = 11,424 millimetres.
Questions
What is 1428 × 12?
17,136.
What is half of 1428 × 8?
1428 × 8 = 11,424, and half of that is 5,712, which is 1428 × 4. Halving one factor halves the answer.
What is 1428 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1428 contain nothing.
What is 1428 × 7 and 1428 × 8?
1428 × 7 = 9,996 and 1428 × 8 = 11,424. These two are the facts most people find hardest, so they are worth practising on their own.
Is 21,420 in the 1428 times table?
Yes: 21,420 ÷ 1428 = 15 with no remainder. 21,421 is not, because dividing it by 1428 leaves a remainder of 1.
How do I learn the 1428 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.
