Patterns that help you remember it
- The last digits repeat in a cycle of 1: 0.
- Every answer is even, because 780 is even.
- Every answer ends in 0 or 5.
- Split it into tens and ones: 780 × k = 780 × k + 0 × k.
- Each answer is 780 more than the one before, so you can count on in steps of 780.
Building it from tables you already know
Every answer in the 780 times table is double the answer in the 390 times table: 390 × 6 = 2,340, so 780 × 6 = 4,680. To multiply 780 by 9, multiply by 10 and take one 780 away: 7,800 − 780 = 7,020. To multiply by 11, multiply by 10 and add one more 780: 7,800 + 780 = 8,580. Multiplying by 4 is doubling twice: 780 → 1,560 → 3,120.
Every multiple of 780 is at least 780, so there are none below 100 and 1 below 1,000. A number is in the 780 times table exactly when it divides by 780 with no remainder.
Odd, even and the last digit
Because 780 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: 780 × 10 = 7,800, and 780 × 100 = 78,000. Multiplying by 5 is half of multiplying by 10: half of 7,800 is 3,900.
Using the 780 times table to divide
Every fact also works backwards: because 780 × 7 = 5,460, you know 5,460 ÷ 780 = 7 and 5,460 ÷ 7 = 780. 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 780 pencils. How many pencils are in 3 boxes?
Answer
3 × 780 = 2,340 pencils. - Tickets cost $780 each. How much do 12 tickets cost?
Answer
12 × $780 = $9,360. - 3,900 chairs are set out in rows of 780. How many rows are there?
Answer
3,900 ÷ 780 = 5 rows. - A plant grows 780 millimetres a week. How much does it grow in 10 weeks?
Answer
10 × 780 = 7,800 millimetres.
Questions
What is 780 × 12?
9,360.
What is half of 780 × 8?
780 × 8 = 6,240, and half of that is 3,120, which is 780 × 4. Halving one factor halves the answer.
What is 780 times 0?
0. Any number multiplied by zero is zero, because zero groups of 780 contain nothing.
What is 780 × 7 and 780 × 8?
780 × 7 = 5,460 and 780 × 8 = 6,240. These two are the facts most people find hardest, so they are worth practising on their own.
Is 11,700 in the 780 times table?
Yes: 11,700 ÷ 780 = 15 with no remainder. 11,701 is not, because dividing it by 780 leaves a remainder of 1.
How do I learn the 780 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.
