Solve the programming task below in a Python markdown code block.
Your task is to create function```isDivideBy``` (or ```is_divide_by```) to check if an integer number is divisible by each out of two arguments.

A few cases:

```

(-12, 2, -6)  ->  true
(-12, 2, -5)  ->  false

(45, 1, 6)    ->  false
(45, 5, 15)   ->  true

(4, 1, 4)     ->  true
(15, -5, 3)   ->  true

```
Also feel free to reuse/extend the following starter code:
```python
def is_divide_by(number, a, b):
```
