Answer to Problem 23E
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144.
Explanation of Solution
Given Information: Number 144
To find factors of a number , find the LCM of the respective number by finding the divisors of it. The factors of 144 are the numbers which can divide the number 144 completely.
Calculation:
Since the Factors of 144 are all the numbers that can evenly divide into 144, simply need to divide 144 by all numbers up to 144 to see which ones result in an even quotient.
The Positive Factors of 144 are therefore all the numbers used to divide (divisors) above to get an even number. Here is the list of all Positive Factors of 144 in numerical order:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144.
