WebRule: A number is divisible by 4 if the number's last two digits are divisible by 4. 9,3 12, for instance, is divisible by 4 since its last 2 digits are 12. And 12 is divisible by 4. Examples … Web• If n has four or more digits and n = 1000a + b where b has three or fewer digits (i.e., b < 100) , then n a + b. • If n has three or fewer digits and n = 1000a + b where b has two or fewer digits (i.e., b < 100) , then n -> b − 8a. (1) n = 123456. We now obtain: 123456 -> 123 + 456 = 579. Next: 579 -> 79− (8×5)=79−40=39.
