#### Steps to find Prime Factors of 1003 by Division Method

To find the primefactors of 1003 using the division method, follow these steps:

• Step 1. Start dividing 1003 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 1003, which is 17. Divide 1003 by 17 to obtain the quotient (59).
1003 ÷ 17 = 59
• Step 3. Repeat step 1 with the obtained quotient (59).
59 ÷ 59 = 1

So, the prime factorization of 1003 is, 1003 = 17 x 59.

#### Steps to find Prime Factors of 1003 by Factor Tree Method

We can follow the same procedure using the factor tree of 1003 as shown below:

So, the prime factorization of 1003 is, 1003 = 17 x 59.

#### 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 1003 are 17 x 59.

#### Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• 2 is the only even prime number. So, any given number can have only one even prime factor and that is 2.
• Two prime factors of a given number 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 1003 but not a prime factor of 1003.
