Patterns that help you remember it
- The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
- Split it into tens and ones: 1581 × k = 1580 × k + 1 × k.
- Each answer is 1581 more than the one before, so you can count on in steps of 1581.
Building it from tables you already know
To multiply 1581 by 9, multiply by 10 and take one 1581 away: 15,810 − 1581 = 14,229. To multiply by 11, multiply by 10 and add one more 1581: 15,810 + 1581 = 17,391. Multiplying by 4 is doubling twice: 1581 → 3,162 → 6,324.
Every multiple of 1581 is at least 1581, so there are none below 100 and 0 below 1,000. A number is in the 1581 times table exactly when it divides by 1581 with no remainder.
Odd, even and the last digit
Because 1581 is odd, the answers alternate between odd and even: 1581 × 1 = 1581 is odd, 1581 × 2 = 3,162 is even, and so on. Multiplying by 10 always puts a zero on the end: 1581 × 10 = 15,810, and 1581 × 100 = 158,100. Multiplying by 5 is half of multiplying by 10: half of 15,810 is 7,905.
Using the 1581 times table to divide
Every fact also works backwards: because 1581 × 7 = 11,067, you know 11,067 ÷ 1581 = 7 and 11,067 ÷ 7 = 1581. Practising the table and its division facts together halves the work.
