Divisibility streak
WebAug 24, 2024 · The divisibility rule for 13 is to add four times the last digit of the number to the remaining number until a two-digit number is obtained. If the two-digit number is divisible by 13, the number too is divisible by 13. For example, Take 1001. Adding 4 to 100, 100 + 4 = 104. Adding 16 to 10, 10 + 16 = 26. WebJul 17, 2024 · Step 1: Add the individual digits of the number. Step 2: If there is more than one digit after adding all the digits, repeat this process until you get a single digit. If the final sum is 9, write 0, because 9 and 0 are equivalent in digital roots (since the remainder is a number smaller than 9).

WebJan 19, 2015 · Congruences allow for a very simple proof of the assertion: ‘ If a 2 is divisible by 3, the a is divisible by 3. It suffices to draw up the list of squares modulo 3: if a ≡ 0 mod 3, then a 2 ≡ 0 2 = 0; if a ≡ ± 1, then a 2 ≡ 1 mod 3 . Hence the only case when a 2 is divisible by 3 is when a itself is. Share.
