Is 92 a Prime Number?

Since 92 has 6 factors, it is not a prime number.

The basic methods to check if a number is prime are the counting divisors method, divisibility method, prime number chart, and prime factorization.

This method will find the total number of divisors of the given number.  If there are more than two divisors, then the given number is composite, not prime.

The divisors of 92 = 1, 2, 4, 23, 46, 92

Therefore, 92 is not prime
 

The divisibility method determines whether a number is composite or not. Make use of the divisibility rule of 2 (if the number is even), the divisibility rule of 3 (if the sum of digits is a multiple of 3), and so on.  

The number 92 is an even number, so we can find the divisors of 92 using the divisibility rule of 2. Hence, factors of 92 are 1, 2, 4, 23, 46 and 92.
 

This method will check if a number is prime or not with the help of a prime number chart. Only if the number is seen in the chart, then it's a prime

Prime Factorization expresses the product of prime factors of composite numbers in exponential form. The prime factors of 92 are 2 and 23. 

The prime factorization of 92 → 2² × 23

Hence, the prime factors of 92 are 2 and 23

• Prime Number: Natural number with two factors. For example, numbers like 3, 5, 19, 91, etc.

• Composite Number: Numbers with more than two factors. For example, numbers like 56, 100, 144, and so on.

• Prime Factorization: Method to express the product of prime factors using exponents.
