#### Steps to find Prime Factors of 516 by Division Method

To find the primefactors of 516 using the division method, follow these steps:

• Step 1. Start dividing 516 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 516, which is 2. Divide 516 by 2 to obtain the quotient (258).
516 ÷ 2 = 258
• Step 3. Repeat step 1 with the obtained quotient (258).
258 ÷ 2 = 129
129 ÷ 3 = 43
43 ÷ 43 = 1

So, the prime factorization of 516 is, 516 = 2 x 2 x 3 x 43.

#### Steps to find Prime Factors of 516 by Factor Tree Method

We can follow the same procedure using the factor tree of 516 as shown below:

So, the prime factorization of 516 is, 516 = 2 x 2 x 3 x 43.

#### 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 516 are 2 x 2 x 3 x 43.

#### Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• Any number can have only 1 even prime factor and that is number 2.
• Two prime factors are always coprime to each other.
• 1 is the factor of any given number, but 1 is neither a prime number nor a composite number. So, 1 is the factor of 516 but not a prime factor of 516.
