Prime Factors of 144

Steps to find Prime Factors of 144 by Division Method

To find the primefactors of 144 using the division method, follow these steps:

• Step 1. Start dividing 144 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 144, which is 2. Divide 144 by 2 to obtain the quotient (72).
  144 ÷ 2 = 72
• Step 3. Repeat step 1 with the obtained quotient (72).
  72 ÷ 2 = 36
  36 ÷ 2 = 18
  18 ÷ 2 = 9
  9 ÷ 3 = 3
  3 ÷ 3 = 1

So, the prime factorization of 144 is, 144 = 2 x 2 x 2 x 2 x 3 x 3.

Steps to find Prime Factors of 144 by Factor Tree Method

We can follow the same procedure using the factor tree of 144 as shown below:

So, the prime factorization of 144 is, 144 = 2 x 2 x 2 x 2 x 3 x 3.

What does Prime factor of a number mean?

A prime number in mathematics is defined as any natural number greater than 1, that is not divisible by any number except 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 144 are 2 x 2 x 2 x 2 x 3 x 3.

Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• Any number can have only 1 even prime factor and that is number 2.
• Two prime factors are always coprime to each other.
• 1 is the factor of any given number, but 1 is neither a prime number nor a composite number. So, 1 is the factor of 144 but not a prime factor of 144.
