What is 10101 divisible by?

Answer 1

To determine if 10101 is divisible by a certain number, we can use the rules of divisibility. For example, to check if 10101 is divisible by 2, we look at the last digit, which is 1 (an odd number), so it is not divisible by 2. To check if it is divisible by 3, we add up the digits (1+0+1+0+1 = 3), and since the sum is divisible by 3, 10101 is divisible by 3. Similarly, we can apply rules for other numbers like 5, 7, etc., to determine their divisibility.

Answer 2

1, 3, 7, 13, 21, 37, 39, 91, 111, 259, 273, 481, 777, 1443, 3367, 10101

Answer 3

Since the digital root is 3, it is divisible by 3.
