Steps to find Prime Factors of 445 by Division Method

To find the primefactors of 445 using the division method, follow these steps:

  • Step 1. Start dividing 445 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 445, which is 5. Divide 445 by 5 to obtain the quotient (89).
    445 ÷ 5 = 89
  • Step 3. Repeat step 1 with the obtained quotient (89).
    89 ÷ 89 = 1

So, the prime factorization of 445 is, 445 = 5 x 89.

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 445 are 5 x 89.

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 445 but not a prime factor of 445.
