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 1798 is even.
- Split it into tens and ones: 1798 × k = 1790 × k + 8 × k.
- Each answer is 1798 more than the one before, so you can count on in steps of 1798.
Building it from tables you already know
Every answer in the 1798 times table is double the answer in the 899 times table: 899 × 6 = 5,394, so 1798 × 6 = 10,788. To multiply 1798 by 9, multiply by 10 and take one 1798 away: 17,980 − 1798 = 16,182. To multiply by 11, multiply by 10 and add one more 1798: 17,980 + 1798 = 19,778. Multiplying by 4 is doubling twice: 1798 → 3,596 → 7,192.
Every multiple of 1798 is at least 1798, so there are none below 100 and 0 below 1,000. A number is in the 1798 times table exactly when it divides by 1798 with no remainder.
Odd, even and the last digit
Because 1798 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: 1798 × 10 = 17,980, and 1798 × 100 = 179,800. Multiplying by 5 is half of multiplying by 10: half of 17,980 is 8,990.
Using the 1798 times table to divide
Every fact also works backwards: because 1798 × 7 = 12,586, you know 12,586 ÷ 1798 = 7 and 12,586 ÷ 7 = 1798. Practising the table and its division facts together halves the work.
