To find the greatest common factor of 42 & 108
Answer to Problem 8CT
Greatest Common Factor is 6. Hence not relatively prime.
Explanation of Solution
Given information:
Numbers 42 & 108
Formula Used: Factorization
Calculation:
Here, break both the numbers into its factors respectively.
So, 42 may be written as
And 108 may be written as
As can be seen that
When the greatest common factor of two numbers is 1- they are said to be relatively prime.
Since their GCF is not 1, 32 & 90 are not relatively prime numbers.
Conclusion-
Greatest Common Factor is 6. Hence not relatively prime.
