Prime Factors of 369

Steps to find Prime Factors of 369 by Division Method

To find the primefactors of 369 using the division method, follow these steps:

• Step 1. Start dividing 369 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 369, which is 3. Divide 369 by 3 to obtain the quotient (123).
  369 ÷ 3 = 123
• Step 3. Repeat step 1 with the obtained quotient (123).
  123 ÷ 3 = 41
  41 ÷ 41 = 1

So, the prime factorization of 369 is, 369 = 3 x 3 x 41.

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 369 are 3 x 3 x 41.

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 369 but not a prime factor of 369.
