Steps to find Prime Factors of 21904 by Division Method

To find the primefactors of 21904 using the division method, follow these steps:

  • Step 1. Start dividing 21904 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 21904, which is 2. Divide 21904 by 2 to obtain the quotient (10952).
    21904 ÷ 2 = 10952
  • Step 3. Repeat step 1 with the obtained quotient (10952).
    10952 ÷ 2 = 5476
    5476 ÷ 2 = 2738
    2738 ÷ 2 = 1369
    1369 ÷ 37 = 37
    37 ÷ 37 = 1

So, the prime factorization of 21904 is, 21904 = 2 x 2 x 2 x 2 x 37 x 37.

What does Prime factor of a number mean?

A prime number in mathematics is defined as any natural number greater than 1, that is not divisible by any number except 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 21904 are 2 x 2 x 2 x 2 x 37 x 37.

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 21904 but not a prime factor of 21904.
