To find the greatest common factor and also find if they are relatively prime or not.
Answer to Problem 25E
1, yes
Explanation of Solution
Given Information:121, 280
Formula used: GCF using Factorization method. Pairs of relatively primes are only divisible by 1.
Calculation:
The factors of 121 are:
The factors of 280 are:
Since there is nothing common between the two numbers, then the greatest common factor is 1.
Since they do have their GCF as 1, they are relatively prime numbers..
