Facts about Natural numbers 

1. The natural numbers are the ordinary numbers, 1, 2, 3, etc., with which we count.
2. The next possible natural number can be found by adding 1 to the current natural number
3. The number zero is sometimes considered to be a natural number. Not always because no one counts starting with zero, 0, 1, 2, 3.
4. GCD of all other natural numbers with a prime is always one.
5. The natural numbers can be defined formally by relating them to sets. Then, zero is the number of elements in the empty set; 1 is the number of elements in the set containing one natural number; and so on.
