By definition, 1 is not prime. A prime number has exactly two unique natural number divisors; itself and one. You can understand '1 and 1' to be two numbers, but they are not unique. The same reasoning brings us to the conclusion that 1 is not composite; a composite number can be divided without remainder by at least one integer other than itself and 1.
A prime number is a positive whole number (a positive integer) that has exactly two unique positive divisors, 1 and the number itself.
The fundamental theorem of arithmetic or the unique factorisation theorem would fail.
Every whole number is unique: no two whole numbers are the same!
1 is the only number that goes into 71 and 100.
unique number: The number 1 has only one factor. (It is therefore unique.)
The number one has the unique property of multiplicative identity: any number times 1 is the same number.
1/0
Every number is a unique number.
Multiplicative identity: There exists a unique nonzero real number 1 (one) such that 1 x a = a x 1 = a.
It is a Composite Number when it can be divided evenly by numbers other than 1 or itself.It is a Prime Number when it can't be divided evenly by any number (except 1 or itself).

Any number can be multiplied by itself, but one is unique in that it stays the same. 1x1 is 1

The atomic number of an element is equal to the number of protons in its nucleus. This number determines an element's position on the periodic table and is unique to each element.
