Why is the greatest common factor of two numbers sometimes 1?
All numbers have a common factor of 1. Sometimes that's the only common factor.
What do you call a number that's neither prime or composite?
One.By definition numbers are:prime if they have only 2 distinct factors (namely 1 and the number itself);composite if they have 3 or more distinct factorsThe important thing to note is the word distinct. The number 1 has only 1 distinct factor, namely 1; thus it is neither a prime (the first prime number is 2) nor composite.
What Has only 1 and itself as a factor?
Prime Numbers
Is it true that two distinct prime numbers can are relatively prime?
It is true. Two numbers are relatively prime if they do not have any factors in common greater than 1. A prime number has only two factors - 1 and itself. Thus, two different prime numbers will only have 1 as a common factor, which means they are relatively prime.
What are two relatively prime numbers?
Numbers whose only common factor is 1.
