Prime Factors of 153

Steps to find Prime Factors of 153 by Division Method

To find the primefactors of 153 using the division method, follow these steps:

• Step 1. Start dividing 153 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 153, which is 3. Divide 153 by 3 to obtain the quotient (51).
  153 ÷ 3 = 51
• Step 3. Repeat step 1 with the obtained quotient (51).
  51 ÷ 3 = 17
  17 ÷ 17 = 1

So, the prime factorization of 153 is, 153 = 3 x 3 x 17.

What does Prime factor in mathematics mean?

Prime numbers, in mathematics are all those whole numbers greater than 1 having exactly two divisors that is 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 153 are 3 x 3 x 17.

Properties of Prime Factors

• Prime factors are the set of factors that are unique to the number given.
• 2 is the only even prime factor any number can have.
• Two prime factors 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 153 but not a prime factor of 153.
