Is 135 a Prime Number?
Do you feel like checking for prime numbers can be tricky? Determining a prime number is easy. Prime numbers are used in encryption. Here, we discuss the topic called ‘Is 135 a prime number?’.
Why is 135 not a Prime Number?
Since 135 has 8 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.
Using the Counting Divisors Method
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 135 = 1, 3, 5, 9, 15, 27, 45, 135
Therefore, 135 is not prime.
Using the Divisibility Test Method
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 135 is divisible by 3 and 5, we use the divisibility rule of 3 and 5. Hence, factors of 135 are 1, 3, 5, 9, 15, 27, 45 and 135
Using Prime Number Chart
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.
Using the Prime Factorization Method
Prime Factorization expresses the product of prime factors of composite numbers in exponential form. The prime factors of 135 are 3 and 5.
The prime factorization of 135 → 33 × 51
