Prime Factors of 80

Steps to find Prime Factors of 80 by Division Method

To find the primefactors of 80 using the division method, follow these steps:

• Step 1. Start dividing 80 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 80, which is 2. Divide 80 by 2 to obtain the quotient (40).
  80 ÷ 2 = 40
• Step 3. Repeat step 1 with the obtained quotient (40).
  40 ÷ 2 = 20
  20 ÷ 2 = 10
  10 ÷ 2 = 5
  5 ÷ 5 = 1

So, the prime factorization of 80 is, 80 = 2 x 2 x 2 x 2 x 5.

Steps to find Prime Factors of 80 by Factor Tree Method

We can follow the same procedure using the factor tree of 80 as shown below:

So, the prime factorization of 80 is, 80 = 2 x 2 x 2 x 2 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 80 are 2 x 2 x 2 x 2 x 5.

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 80 but not a prime factor of 80.
