Steps to find Prime Factors of 802 by Division Method

To find the primefactors of 802 using the division method, follow these steps:

  • Step 1. Start dividing 802 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 802, which is 2. Divide 802 by 2 to obtain the quotient (401).
    802 ÷ 2 = 401
  • Step 3. Repeat step 1 with the obtained quotient (401).
    401 ÷ 401 = 1

So, the prime factorization of 802 is, 802 = 2 x 401.

Steps to find Prime Factors of 802 by Factor Tree Method

We can follow the same procedure using the factor tree of 802 as shown below:

So, the prime factorization of 802 is, 802 = 2 x 401.

How do you define Prime Factors of a number?

Prime numbers, in mathematics are all those natural numbers greater than 1 that have exactly 2 factors which are 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 802 are 2 x 401.

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 802 but not a prime factor of 802.
