# Checking whether array elements can be made equal

## Question

Given an array `a`

, write a function to feed in the array elements and check whether they can all be made equal by only multiplying the numbers by `2`

or `7`

. *(you can multiply by these #s as many times as you like)*

If all elements can be made equal, return `False`

, otherwise return `True`

.

Example:

```
#Input
a = [128, 4, 2]
#Here, we can turn all elements into 128, by multiplying by 2
#128, 4*2*2*2*2*2 = 128, 2*2*2*2*2*2*2 = 128
#Output:
#True
#Input
a = [65, 4, 2]
#Here, we cannot make all elements equal through multiplication by 2 or 7,
#so we return false
#Output:
#False
```
