Prime Factors of 1275

Steps to find Prime Factors of 1275 by Division Method

To find the primefactors of 1275 using the division method, follow these steps:

• Step 1. Start dividing 1275 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 1275, which is 3. Divide 1275 by 3 to obtain the quotient (425).
  1275 ÷ 3 = 425
• Step 3. Repeat step 1 with the obtained quotient (425).
  425 ÷ 5 = 85
  85 ÷ 5 = 17
  17 ÷ 17 = 1

So, the prime factorization of 1275 is, 1275 = 3 x 5 x 5 x 17.

Steps to find Prime Factors of 1275 by Factor Tree Method

We can follow the same procedure using the factor tree of 1275 as shown below:

So, the prime factorization of 1275 is, 1275 = 3 x 5 x 5 x 17.

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 1275 are 3 x 5 x 5 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 1275 but not a prime factor of 1275.
