Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 1380 is even.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 1380 × k = 1380 × k + 0 × k.
- Each answer is 1380 more than the one before, so you can count on in steps of 1380.
Building it from tables you already know
Every answer in the 1380 times table is double the answer in the 690 times table: 690 × 6 = 4,140, so 1380 × 6 = 8,280. To multiply 1380 by 9, multiply by 10 and take one 1380 away: 13,800 − 1380 = 12,420. To multiply by 11, multiply by 10 and add one more 1380: 13,800 + 1380 = 15,180. Multiplying by 4 is doubling twice: 1380 → 2,760 → 5,520.
Every multiple of 1380 is at least 1380, so there are none below 100 and 0 below 1,000. A number is in the 1380 times table exactly when it divides by 1380 with no remainder.
Odd, even and the last digit
Because 1380 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: 1380 × 10 = 13,800, and 1380 × 100 = 138,000. Multiplying by 5 is half of multiplying by 10: half of 13,800 is 6,900.
Using the 1380 times table to divide
Every fact also works backwards: because 1380 × 7 = 9,660, you know 9,660 ÷ 1380 = 7 and 9,660 ÷ 7 = 1380. 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 1380 pencils. How many pencils are in 5 boxes?
Answer
5 × 1380 = 6,900 pencils. - Tickets cost $1380 each. How much do 10 tickets cost?
Answer
10 × $1380 = $13,800. - 2,760 chairs are set out in rows of 1380. How many rows are there?
Answer
2,760 ÷ 1380 = 2 rows. - A plant grows 1380 millimetres a week. How much does it grow in 9 weeks?
Answer
9 × 1380 = 12,420 millimetres.
Questions
What is 1380 × 12?
16,560.
What is half of 1380 × 8?
1380 × 8 = 11,040, and half of that is 5,520, which is 1380 × 4. Halving one factor halves the answer.
What is 1380 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1380 contain nothing.
What is 1380 × 7 and 1380 × 8?
1380 × 7 = 9,660 and 1380 × 8 = 11,040. These two are the facts most people find hardest, so they are worth practising on their own.
Is 20,700 in the 1380 times table?
Yes: 20,700 ÷ 1380 = 15 with no remainder. 20,701 is not, because dividing it by 1380 leaves a remainder of 1.
How do I learn the 1380 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.
