#### Steps to find Prime Factors of 1188 by Division Method

To find the primefactors of 1188 using the division method, follow these steps:

• Step 1. Start dividing 1188 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 1188, which is 2. Divide 1188 by 2 to obtain the quotient (594).
1188 ÷ 2 = 594
• Step 3. Repeat step 1 with the obtained quotient (594).
594 ÷ 2 = 297
297 ÷ 3 = 99
99 ÷ 3 = 33
33 ÷ 3 = 11
11 ÷ 11 = 1

So, the prime factorization of 1188 is, 1188 = 2 x 2 x 3 x 3 x 3 x 11.

#### Steps to find Prime Factors of 1188 by Factor Tree Method

We can follow the same procedure using the factor tree of 1188 as shown below:

So, the prime factorization of 1188 is, 1188 = 2 x 2 x 3 x 3 x 3 x 11.

#### 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 1188 are 2 x 2 x 3 x 3 x 3 x 11.

#### 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 1188 but not a prime factor of 1188.
