If any number's digits add up to a multiple of 3, then that number is a multiple of 3. For this number, 6 + 9 + 3 = 18, and 18 is a multiple of 3 (if we didn't know that, we could see that 1 + 8 = 9, which is a multiple of 3). That means we can divide 693 by 3, and we get 231. Is 231 divisible by 3? Well, 2 + 3 + 1 = 6, so it is. Divide 231 by 3 and you get 77. That means 77 * 3 * 3 = 693.
