Can a number be relatively prime to itself?
Two number are said to be "relatively prime" if they have no common factors - of course, other than the trivial factor 1. Even a prime number is not "relatively prime" to itself, since the prime number itself is the common factor. For example, the common factor of 7 and 7 is 7. Thus, the only situation I can think of where a number has no common factor with itself is that the number is 1.

What are the greatest common factors of 7 42 70?
The greatest common factor (GCF) of 7, 42, and 70 is 7. To find the GCF, you need to identify the largest number that divides evenly into all three numbers. In this case, 7 is the largest number that can divide 7, 42, and 70 without leaving a remainder. Therefore, the GCF of 7, 42, and 70 is 7.
