I don't understand how to determine whether a natural number is divisible.
In example: is 235 divisible by 2,3, 5?
------------------
You can use a calculator.
235 = 5*47
------------
Any number ending in 5 or 0 is divisible by 5.
If it's even, it's divisible by 2.

There are at least three ways:
1-Find all of the factors of 235
You should know that 5 is a factor since multiples of 5 end in 0 and 5
so divide 235 by 5 and get 47
which is prime
There are two 5 and 47 both prime.
2-You should know that 2 is not a factor because 235 is not even
3-Divide 235 by each number
