#### Steps to find Prime Factors of 1098 by Division Method

To find the primefactors of 1098 using the division method, follow these steps:

• Step 1. Start dividing 1098 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 1098, which is 2. Divide 1098 by 2 to obtain the quotient (549).
1098 ÷ 2 = 549
• Step 3. Repeat step 1 with the obtained quotient (549).
549 ÷ 3 = 183
183 ÷ 3 = 61
61 ÷ 61 = 1

So, the prime factorization of 1098 is, 1098 = 2 x 3 x 3 x 61.

#### Steps to find Prime Factors of 1098 by Factor Tree Method

We can follow the same procedure using the factor tree of 1098 as shown below:

So, the prime factorization of 1098 is, 1098 = 2 x 3 x 3 x 61.

#### 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 1098 are 2 x 3 x 3 x 61.

#### 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 1098 but not a prime factor of 1098.
