  • Divide 693 by 693: 693 ÷ 693 : Remainder = 0

Hence, Factors of 693 are 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, and 693

2. Steps to find factors of 693 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

Method 1: Division Method

To find the primefactors of 693 using the division method, follow these steps:

  • Step 1. Start dividing 693 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 693, which is 3. Divide 693 by 3 to obtain the quotient (231).
    693 ÷ 3 = 231
  • Step 3. Repeat step 1 with the obtained quotient (231).
    231 ÷ 3 = 77
    77 ÷ 7 = 11
    11 ÷ 11 = 1

So, the prime factorization of 693 is, 693 = 3 x 3 x 7 x 11.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 693 as shown below:

So, the prime factorization of 693 is, 693 = 3 x 3 x 7 x 11.

3. Find factors of 693 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 693 would be the two numbers which, when multiplied, give 693 as the result.

The following table represents the calculation of factors of 693 in pairs:

Factor Pair Pair Factorization
1 and 693 1 x 693 = 693
3 and 231 3 x 231 = 693
7 and 99 7 x 99 = 693
9 and 77 9 x 77 = 693
11 and 63 11 x 63 = 693
21 and 33 21 x 33 = 693

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 693. They are called negative pair factors.

Hence, the negative pairs of 693 would be ( -1 , -693 ) , ( -3 , -231 ) , ( -7 , -99 ) , ( -9 , -77 ) , ( -11 , -63 ) and ( -21 , -33 ) .

What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

Properties of factors

  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 693 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 693.
