To find factors of number 87

Answer to Problem 4C
1, 3, 29 and 87
Explanation of Solution
Given Information:
Number 87
Calculation: To find factors of a number find the LCM of the respective number by finding the divisors of it. The factors of 87 are the numbers which can divide the number 87 completely.
Since the Factors of 87 are all the numbers that you can evenly divide into 87, simply need to divide 87 by all numbers up to 87 to see which ones result in an even quotient.
The Positive Factors of 87 are therefore all the numbers used to divide (divisors) above to get an even number. Here is the list of all Positive Factors of 87 in numerical order:
1, 3, 29, and 87.
