Question

Write all the factors of the following number 23.

Answer 1

Hint: This type of problem is based on the concept of factoring a number. First, we have to consider the given number. We then have to check whether the function is a prime or composite number. Here, we find that 23 is a prime number. We know that the factors of a prime number are 1 and itself. Thus, we get the factors of 23 as 1 and 23 which is the required answer.

Complete step by step solution:
According to the question, we are asked to find the factors of the number 23.
We have been given the number 23.
First let us consider the given number.
We have to check whether the function is a prime number or composite number.
According to the definition of prime numbers, we know that prime numbers are divisible only by 1 and itself.
And according to the definition of composite numbers, we get that a composite number can be expressed as a product of prime numbers.
But here we find that 23 cannot be expressed as the factors of prime numbers.
Therefore, we find that 23 is a prime number.
We know that the factors of prime numbers are 1 and itself.
Thus, we get the factors of 23 are 1 and 23.
Therefore, the factors of 23 are 1 and 23.

Note:
We can find whether the given number is prime or composite by trial and error methods. Divide the number with the prime numbers less than the considered number. If the number is exactly divisible by any prime number, it is a composite number. If not, it is then a prime number.
