Prime Factors of 51

Steps to find Prime Factors of 51 by Division Method

To find the primefactors of 51 using the division method, follow these steps:

• Step 1. Start dividing 51 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 51, which is 3. Divide 51 by 3 to obtain the quotient (17).
  51 ÷ 3 = 17
• Step 3. Repeat step 1 with the obtained quotient (17).
  17 ÷ 17 = 1

So, the prime factorization of 51 is, 51 = 3 x 17.

Steps to find Prime Factors of 51 by Factor Tree Method

We can follow the same procedure using the factor tree of 51 as shown below:

So, the prime factorization of 51 is, 51 = 3 x 17.

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 51 are 3 x 17.

Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• 2 is the only even prime number. So, any given number can have only one even prime factor and that is 2.
• Two prime factors of a given number 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 51 but not a prime factor of 51.
