Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 1620 is even.
- The digits of every answer add up to a multiple of 9.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 1620 × k = 1620 × k + 0 × k.
- Each answer is 1620 more than the one before, so you can count on in steps of 1620.
Building it from tables you already know
Every answer in the 1620 times table is double the answer in the 810 times table: 810 × 6 = 4,860, so 1620 × 6 = 9,720. To multiply 1620 by 9, multiply by 10 and take one 1620 away: 16,200 − 1620 = 14,580. To multiply by 11, multiply by 10 and add one more 1620: 16,200 + 1620 = 17,820. Multiplying by 4 is doubling twice: 1620 → 3,240 → 6,480.
Every multiple of 1620 is at least 1620, so there are none below 100 and 0 below 1,000. A number is in the 1620 times table exactly when it divides by 1620 with no remainder.
Odd, even and the last digit
Because 1620 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: 1620 × 10 = 16,200, and 1620 × 100 = 162,000. Multiplying by 5 is half of multiplying by 10: half of 16,200 is 8,100.
Using the 1620 times table to divide
Every fact also works backwards: because 1620 × 7 = 11,340, you know 11,340 ÷ 1620 = 7 and 11,340 ÷ 7 = 1620. 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 1620 pencils. How many pencils are in 7 boxes?
Answer
7 × 1620 = 11,340 pencils. - Tickets cost $1620 each. How much do 5 tickets cost?
Answer
5 × $1620 = $8,100. - 4,860 chairs are set out in rows of 1620. How many rows are there?
Answer
4,860 ÷ 1620 = 3 rows. - A plant grows 1620 millimetres a week. How much does it grow in 6 weeks?
Answer
6 × 1620 = 9,720 millimetres.
Questions
What is 1620 × 12?
19,440.
What is half of 1620 × 8?
1620 × 8 = 12,960, and half of that is 6,480, which is 1620 × 4. Halving one factor halves the answer.
What is 1620 times 0?
0. Any number multiplied by zero is zero, because zero groups of 1620 contain nothing.
What is 1620 × 7 and 1620 × 8?
1620 × 7 = 11,340 and 1620 × 8 = 12,960. These two are the facts most people find hardest, so they are worth practising on their own.
Is 24,300 in the 1620 times table?
Yes: 24,300 ÷ 1620 = 15 with no remainder. 24,301 is not, because dividing it by 1620 leaves a remainder of 1.
How do I learn the 1620 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.
