Why is 1709 a prime number?
A number to be a prime number should follow the criteria that it should have no factors other than 1 and itself. Here, 1709 has only 2 factors, making it a prime number.
Given below are a few ways that can be used to identify whether a number is a prime number or not.
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
For the counting divisors method, it is checked whether the number is divisible by any numbers other than 1 and the number itself.
The counting divisors method for 1709 would simply be:
Divisors of 1709 = 1, 1709
Number of divisors = 2
The number 1709 can be considered a prime number.
Using the Divisibility Method
In the divisibility test, we try to divide the number by any of the smaller prime numbers. If we cannot divide it without a remainder, the number is considered a prime number.
For 1709, no prime number (other than 1 and 1709 itself) divides it completely without leaving a remainder. Hence, 1709 is a prime number.
Using the Prime Number Chart
The prime number chart is a list of prime numbers starting from 2 to infinity.
The list of prime numbers from 1700 to 1800 are:
1709, 1721, 1723, 1733, 1741, 1747, 1753, 1759, 1777, 1783, 1787, 1789
1709 is present in the list, confirming it is a prime number.
Common mistakes to avoid when determining if 1709 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.
Mistake 1
Misinterpreting all numbers to be prime.
A number being odd does not decide if the number will be prime. An odd number can also be a composite number.
Mistake 2
Skipping out the divisors.
Without checking all the divisors of a number, students incorrectly conclude a number is prime or composite. Avoid doing this.
Mistake 3
Thinking prime numbers should fall in a range only.
Prime numbers do not have a range. As long as the criteria of having 2 divisors is fulfilled, the prime number can be any number.
Mistake 4
Ignoring divisibility rules for smaller prime numbers.
Ensure you check divisibility by smaller prime numbers like 2, 3, 5, 7, and so on. Missing this step can lead to an incorrect conclusion.
Mistake 5
Relying only on mental calculations.
For larger numbers like 1709, relying solely on mental calculations can result in errors. Use systematic methods or tools to verify divisibility.
