#### Steps to find Prime Factors of 666 by Division Method

To find the primefactors of 666 using the division method, follow these steps:

• Step 1. Start dividing 666 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 666, which is 2. Divide 666 by 2 to obtain the quotient (333).
666 ÷ 2 = 333
• Step 3. Repeat step 1 with the obtained quotient (333).
333 ÷ 3 = 111
111 ÷ 3 = 37
37 ÷ 37 = 1

So, the prime factorization of 666 is, 666 = 2 x 3 x 3 x 37.

#### Steps to find Prime Factors of 666 by Factor Tree Method

We can follow the same procedure using the factor tree of 666 as shown below:

So, the prime factorization of 666 is, 666 = 2 x 3 x 3 x 37.

#### Introduction to Prime Factors?

In mathematics, prime numbers are defined as all those natural numbers greater than 1 that has only two divisors one being number 1 and the other being the number itself. When we express any number as the products of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 666 are 2 x 3 x 3 x 37.

#### 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 666 but not a prime factor of 666.

• Is 666 a prime number?
