Patterns that help
The last digits go 5, 0 and then repeat.
15 is odd, so its multiples go odd, even, odd, even: 15, 30, 45, 60.
A quick check: The last digit is 0 or 5 AND the digits add to a multiple of 3, because 15 = 3 × 5. 75 ends in 5, and 7 + 5 = 12, so 75 is a multiple of 15.
Building the list from facts you know: Split 15 into 10 and 5: 15 × 6 is 60 + 30, which is 90.
