Prime Factors of 356

Steps to find Prime Factors of 356 by Division Method

To find the primefactors of 356 using the division method, follow these steps:

• Step 1. Start dividing 356 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 356, which is 2. Divide 356 by 2 to obtain the quotient (178).
  356 ÷ 2 = 178
• Step 3. Repeat step 1 with the obtained quotient (178).
  178 ÷ 2 = 89
  89 ÷ 89 = 1

So, the prime factorization of 356 is, 356 = 2 x 2 x 89.

We can follow the same procedure using the factor tree of 356 as shown below:

So, the prime factorization of 356 is, 356 = 2 x 2 x 89.

Introduction to Prime Factors?

In mathematics, prime numbers are defined as all those natural numbers greater than 1 that has only two divisors one being number 1 and the other being the number itself. When we express any number as the products of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 356 are 2 x 2 x 89.

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 356 but not a prime factor of 356.
