#### Steps to find Prime Factors of 129 by Division Method

To find the primefactors of 129 using the division method, follow these steps:

• Step 1. Start dividing 129 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 129, which is 3. Divide 129 by 3 to obtain the quotient (43).
129 ÷ 3 = 43
• Step 3. Repeat step 1 with the obtained quotient (43).
43 ÷ 43 = 1

So, the prime factorization of 129 is, 129 = 3 x 43.

#### Steps to find Prime Factors of 129 by Factor Tree Method

We can follow the same procedure using the factor tree of 129 as shown below:

So, the prime factorization of 129 is, 129 = 3 x 43.

#### 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 129 are 3 x 43.

#### 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 129 but not a prime factor of 129.
