#### Steps to find Prime Factors of 731 by Division Method

To find the primefactors of 731 using the division method, follow these steps:

• Step 1. Start dividing 731 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 731, which is 17. Divide 731 by 17 to obtain the quotient (43).
731 ÷ 17 = 43
• Step 3. Repeat step 1 with the obtained quotient (43).
43 ÷ 43 = 1

So, the prime factorization of 731 is, 731 = 17 x 43.

#### Steps to find Prime Factors of 731 by Factor Tree Method

We can follow the same procedure using the factor tree of 731 as shown below:

So, the prime factorization of 731 is, 731 = 17 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 731 are 17 x 43.

#### 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 731 but not a prime factor of 731.
