Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement?
The numbers are not relatively prime, because they have a common factor of 2. To simplify, any pair is relatively prime, if their GCD is 1. In this case, GCD(38,40) = 2 which is not equal to 1, thus, they are not relatively prime.
Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect?
Relatively prime numbers only have 1 as a common divisor. 38 and 40 have 1 and 2.
