Is 1501 a prime number?
Prime numbers have only 1 and the number itself as factors. They are used in digital security and in securing digital payments. The topics below will help you gain more knowledge about prime numbers and how they are categorized.
Is 1501 a prime number?
The number 1501 has 4 factors that are capable of dividing the number completely without leaving any remainder. Thus, the number 1501 is a non-prime number. The factors of 1501 include 1, 19, 79, and 1501.
Why is 1501 not a prime number?
For a number to be classified as a prime number, it must have exactly 2 factors: 1 and itself. However, 1501 has more than 2 factors, which makes it a composite number.
Below are a few methods to determine whether a number is prime or composite.
The different methods we can use to check if a number is a prime number are explained below:
- Counting Divisors Method
- Divisibility Test
- Prime Number Chart
- Prime Factorization
Using the Counting Divisors Method
In the counting divisors method, we check whether the number is divisible by any numbers other than 1 and itself.
The counting divisors method for 1501 would simply be:
Divisors of 1501 = 1, 19, 79, 1501
Number of divisors = 4
Since 1501 has more than 2 divisors, it is considered a composite number.
Using the Divisibility Method
In the divisibility method, a prime number will have only 2 divisors: 1 and itself.
The divisors of 1501 are 1, 19, 79, and 1501.
Thus, 1501 consists of 4 factors that divide it completely without any remainder, confirming it is not a prime number.
Using the Prime Number Chart
The prime number chart lists all prime numbers in a given range.
The list of prime numbers from 1500 to 1600 are:
1511, 1523, 1791, 1543, 1549, 1579, 1559, 1567, 1571, 1579, 1583, 1597.
1501 is not present in this list, confirming that it is not a prime number.
Using the Prime Factorization
This method is used specifically for composite numbers. Since 1501 is a composite number, its prime factorization is:
Factors of 1501 = 19 × 79
Thus, 1501 is not a prime number but a composite number.
