Steps to find Prime Factors of 15625 by Division Method

To find the primefactors of 15625 using the division method, follow these steps:

  • Step 1. Start dividing 15625 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 15625, which is 5. Divide 15625 by 5 to obtain the quotient (3125).
    15625 ÷ 5 = 3125
  • Step 3. Repeat step 1 with the obtained quotient (3125).
    3125 ÷ 5 = 625
    625 ÷ 5 = 125
    125 ÷ 5 = 25
    25 ÷ 5 = 5
    5 ÷ 5 = 1

So, the prime factorization of 15625 is, 15625 = 5 x 5 x 5 x 5 x 5 x 5.

So, the prime factorization of 15625 is, 15625 = 5 x 5 x 5 x 5 x 5 x 5.

Definition of Prime Factors?

In mathematics, prime numbers are defined as all those whole numbers greater than 1 that have only two factors, i.e. 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 15625 are 5 x 5 x 5 x 5 x 5 x 5.

Properties of Prime Factors

  • Prime factors are the set of factors that are unique to the number given.
  • 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 15625 but not a prime factor of 15625.
