Steps to find Prime Factors of 28812 by Division Method

To find the primefactors of 28812 using the division method, follow these steps:

  • Step 1. Start dividing 28812 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 28812, which is 2. Divide 28812 by 2 to obtain the quotient (14406).
    28812 ÷ 2 = 14406
  • Step 3. Repeat step 1 with the obtained quotient (14406).
    14406 ÷ 2 = 7203
    7203 ÷ 3 = 2401
    2401 ÷ 7 = 343
    343 ÷ 7 = 49
    49 ÷ 7 = 7
    7 ÷ 7 = 1

So, the prime factorization of 28812 is, 28812 = 2 x 2 x 3 x 7 x 7 x 7 x 7.

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 28812 are 2 x 2 x 3 x 7 x 7 x 7 x 7.

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 28812 but not a prime factor of 28812.
