Prime Factors of 81432

Steps to find Prime Factors of 81432 by Division Method

To find the primefactors of 81432 using the division method, follow these steps:

• Step 1. Start dividing 81432 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 81432, which is 2. Divide 81432 by 2 to obtain the quotient (40716).
  81432 ÷ 2 = 40716
• Step 3. Repeat step 1 with the obtained quotient (40716).
  40716 ÷ 2 = 20358
  20358 ÷ 2 = 10179
  10179 ÷ 3 = 3393
  3393 ÷ 3 = 1131
  1131 ÷ 3 = 377
  377 ÷ 13 = 29
  29 ÷ 29 = 1

So, the prime factorization of 81432 is, 81432 = 2 x 2 x 2 x 3 x 3 x 3 x 13 x 29.

So, the prime factorization of 81432 is, 81432 = 2 x 2 x 2 x 3 x 3 x 3 x 13 x 29.

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 81432 are 2 x 2 x 2 x 3 x 3 x 3 x 13 x 29.

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 81432 but not a prime factor of 81432.
