number

You should know first :

**Factor of N** : All numbers which perfectly divides **N**

Main Logic :

```
for i in range(1, int(num/2)+1) :
if num % i==0 : # Checking for the factor
print(i, end=" ")
print(num)
```

We are running the loop `num/2`

Since, any number can have only factors under its half, except itself
