#### Steps to find Prime Factors of 1161 by Division Method

To find the primefactors of 1161 using the division method, follow these steps:

• Step 1. Start dividing 1161 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 1161, which is 3. Divide 1161 by 3 to obtain the quotient (387).
1161 ÷ 3 = 387
• Step 3. Repeat step 1 with the obtained quotient (387).
387 ÷ 3 = 129
129 ÷ 3 = 43
43 ÷ 43 = 1

So, the prime factorization of 1161 is, 1161 = 3 x 3 x 3 x 43.

#### Steps to find Prime Factors of 1161 by Factor Tree Method

We can follow the same procedure using the factor tree of 1161 as shown below:

So, the prime factorization of 1161 is, 1161 = 3 x 3 x 3 x 43.

#### 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 1161 are 3 x 3 x 3 x 43.

#### 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 1161 but not a prime factor of 1161.
