Steps to find Prime Factors of 489 by Division Method

To find the primefactors of 489 using the division method, follow these steps:

• Step 1. Start dividing 489 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 489, which is 3. Divide 489 by 3 to obtain the quotient (163).
489 ÷ 3 = 163
• Step 3. Repeat step 1 with the obtained quotient (163).
163 ÷ 163 = 1

So, the prime factorization of 489 is, 489 = 3 x 163.

Steps to find Prime Factors of 489 by Factor Tree Method

We can follow the same procedure using the factor tree of 489 as shown below:

So, the prime factorization of 489 is, 489 = 3 x 163.

What does Prime factor of a number mean?

A prime number in mathematics is defined as any natural number greater than 1, that is not divisible by any number except 1 and the number itself. When we express any number as the product of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 489 are 3 x 163.

Properties of Prime Factors

• Prime factors are the set of factors that are unique to the number given.
• 2 is the only even prime factor any number can have.
• Two prime factors are always coprime to each other.
• 1 is neither a prime number nor a composite number and also 1 is the factor of every given number. So, 1 is the factor of 489 but not a prime factor of 489.
