When 2 numbers have their GCF = 1, it means that the numbers are relatively prime to each other, which doesn't necessarily mean that they are prime on their own.
There are 2 cases where relative prime can be guarenteed:
All prime numbers are guarenteed to be relatively prime to all other prime numbers.
Any Prime number is guarenteed to be relatively prime to any composite number smaller than the prime number.
If neither of the above 2 conditions are met, manual calculations must be done to find any existing GCF.

What is the GCF of 31 and 100?
The GCF of these numbers is 1.
What is the GCF of 51 and 175?
The two numbers are coprime so the gcf is 1.
What is the GCF of 71 and 97?
Since both the numbers are prime, their GCF is 1.
What is the GCF of 343 and 512?
GCF(343, 512) = 1; the numbers are coprime.
What is the GCF of 1 and -4?
5
What is the GCF of the 85?
You need at least two numbers to find a GCF.
What is the GCF for these numbers 3 and 5?
The GCF is 1.
What is the GCF of the numbers 32 and 51?
The GCF is 1.
What mean relatively prime numbers?
Two numbers are considered relatively prime when their GCF is 1.
How can you find the gcf of two numbers without knowing the factors?
If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.
Can two numbers in a row have a gcf?
Consecutive numbers have a GCF of 1.
What is the gcf of all composite numbers under 100?
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
What two numbers have 1 as there gcf?
Prime and relatively prime numbers all have a GCF of 1.
What is the GCF of 27 and 64?
The GCF is: 1.
What is the GCF of 35 and 8?
The GCF is 1.
What is the GCF of 51 and 4?
The GCF is 1.
