Prime Factors of 1235

Steps to find Prime Factors of 1235 by Division Method

To find the primefactors of 1235 using the division method, follow these steps:

• Step 1. Start dividing 1235 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 1235, which is 5. Divide 1235 by 5 to obtain the quotient (247).
  1235 ÷ 5 = 247
• Step 3. Repeat step 1 with the obtained quotient (247).
  247 ÷ 13 = 19
  19 ÷ 19 = 1

So, the prime factorization of 1235 is, 1235 = 5 x 13 x 19.

So, the prime factorization of 1235 is, 1235 = 5 x 13 x 19.

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 1235 are 5 x 13 x 19.

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 1235 but not a prime factor of 1235.
