Prime Factors of 7

Steps to find Prime Factors of 7 by Division Method

To find the primefactors of 7 using the division method, follow these steps:

• Step 1. Start dividing 7 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 7, which is 7. Divide 7 by 7 to obtain the quotient (1).
  7 ÷ 7 = 1
• Step 3. Repeat step 1 with the obtained quotient (1).

So, the prime factorization of 7 is, 7 = 7.

Steps to find Prime Factors of 7 by Factor Tree Method

We can follow the same procedure using the factor tree of 7 as shown below:

So, the prime factorization of 7 is, 7 = 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 7 are 7.

Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• 2 is the only even prime number. So, any given number can have only one even prime factor and that is 2.
• Two prime factors of a given number 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 7 but not a prime factor of 7.
