# Java Program to Check if all digits of a number divide it

Given a number n, find whether all digits of n divide it or not.

Examples:

```Input : 128
Output : Yes
128 % 1 == 0, 128 % 2 == 0, and 128 % 8 == 0.

Input : 130
Output : No
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

We want to test whether each digit is non-zero and divides the number. For example, with 128, we want to test d != 0 && 128 % d == 0 for d = 1, 2, 8. To do that, we need to iterate over each digit of the number.

Output:

```Yes
```
