Chapter 4.1, Problem 19E

To determine

To find factors of number 33

Answer to Problem 19E

1, 3, 11, and 33.

Explanation of Solution

Given Information: Number 33

Formula Used: To find factors of a number , find the LCM of the respective number by finding the divisors of it. The factors of 33 are the numbers which can divide the number 33 completely.

Calculation:

Since the Factors of 33 are all the numbers that can evenly divide into 33, simply need to divide 33 by all numbers up to 33 to see which ones result in an even quotient.

  $\begin{array}{l}33÷1=33\\ 33÷3=11\\ 33÷11=3\\ 33÷33=1\end{array}$

The Positive Factors of 33 are therefore all the numbers used to divide (divisors) above to get an even number. Here is the list of all Positive Factors of 33 in numerical order:

1, 3, 11, and 33.
