Using the Divisibility Method

In the division test, we try to divide the number by any of the prime numbers. If we cannot, then it is considered a prime number.


In the divisibility method, the prime number only has 2 divisors, which are 1 and itself.


The divisors of 3187 are 1 and 3187.


Thus, 3187 consists of 2 factors that divide it completely without any remainder.

Using the Prime Number Chart

The prime number chart is the list of prime numbers starting from 2 to infinity.


The list of prime numbers from 3000 to 3200 are:

3001, 3011, 3019, 3023, 3037, 3041, 3049, 3061, 3067, 3079, 3083, 3089, 3109, 3119, 3121, 3137, 3163, 3167, 3169, 3181, 3187, 3191


3187 is present in the list, thus making it a prime number.

Using the Prime Factorization

This method is only used for a non-prime number/composite number. Since 3187 is a prime number, it does not have any prime factorization other than itself. Therefore, 3187 remains as 3187.

Common mistakes to avoid when determining if 3187 is a prime number

It is highly likely we commit some mistakes due to confusion or unclear understanding. Let us look at possible mistakes we may make and try to avoid them.

Glossaries for “Is 3187 a prime number”

  • Prime Number: A number greater than 1 that has exactly two distinct divisors: 1 and the number itself. For example, 3187 is a prime number because it can only be divided by 1 and itself.
  • Divisibility Test: A method used to determine if one number can be evenly divided by another. If a number can be divided without leaving a remainder, it is divisible by that number. This test helps to identify prime numbers by checking divisibility by smaller primes.
  • Divisors: The numbers that can divide a given number completely without leaving a remainder. For example, the divisors of 3187 are 1 and 3187 itself, confirming it is prime.
  • Prime Factorization: The expression of a number as a product of prime numbers. Since 3187 is prime, it cannot be factored further into smaller prime numbers.
  • Composite Number: A natural number greater than 1 that has more than two divisors. Unlike prime numbers, composite numbers can be divided by numbers other than 1 and themselves. 3187 is not composite because it has only two divisors.
