#### Steps to find Prime Factors of 1218 by Division Method

To find the primefactors of 1218 using the division method, follow these steps:

• Step 1. Start dividing 1218 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 1218, which is 2. Divide 1218 by 2 to obtain the quotient (609).
1218 ÷ 2 = 609
• Step 3. Repeat step 1 with the obtained quotient (609).
609 ÷ 3 = 203
203 ÷ 7 = 29
29 ÷ 29 = 1

So, the prime factorization of 1218 is, 1218 = 2 x 3 x 7 x 29.

#### Steps to find Prime Factors of 1218 by Factor Tree Method

We can follow the same procedure using the factor tree of 1218 as shown below:

So, the prime factorization of 1218 is, 1218 = 2 x 3 x 7 x 29.

#### 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 1218 are 2 x 3 x 7 x 29.

#### Properties of Prime Factors

• Two prime factors of a given number are always coprime to each other.
• 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 1218 but not a prime factor of 1218.
