Prime Factors of 187

Steps to find Prime Factors of 187 by Division Method

To find the primefactors of 187 using the division method, follow these steps:

• Step 1. Start dividing 187 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 187, which is 11. Divide 187 by 11 to obtain the quotient (17).
  187 ÷ 11 = 17
• Step 3. Repeat step 1 with the obtained quotient (17).
  17 ÷ 17 = 1

So, the prime factorization of 187 is, 187 = 11 x 17.

Steps to find Prime Factors of 187 by Factor Tree Method

We can follow the same procedure using the factor tree of 187 as shown below:

So, the prime factorization of 187 is, 187 = 11 x 17.

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 187 are 11 x 17.

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 187 but not a prime factor of 187.
