Prime Factors of 654

Steps to find Prime Factors of 654 by Division Method

To find the primefactors of 654 using the division method, follow these steps:

• Step 1. Start dividing 654 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 654, which is 2. Divide 654 by 2 to obtain the quotient (327).
  654 ÷ 2 = 327
• Step 3. Repeat step 1 with the obtained quotient (327).
  327 ÷ 3 = 109
  109 ÷ 109 = 1

So, the prime factorization of 654 is, 654 = 2 x 3 x 109.

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 654 are 2 x 3 x 109.

Properties of Prime Factors

• Two prime factors of a given number are always coprime to each other.
• 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 654 but not a prime factor of 654.
