How do we know if a number is divisible by 4
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. WebJul 6, 2013 · Which means that we can test to see if 344 is divisible by 8 by subtracting 4 from its last two digits, 44 – 4 = 40, and then checking to see if this new number is divisible by 8.
