That's the greatest common factor, or GCF.
It appears that you refer to the Greatest Common Factor.
Two (or more) integers have a common factor - e.g., the greatest common factor of 173 and 100 is 1, or the greatest common factor of 173 and 519 is 173. The question makes no sense with one number. 173 is a prime, by the way.
There has to be 2 or more integers to find the gcf
The greatest common factor of two (or more) integers is the biggest whole number that divides into each one of them. The least common factor is the smallest whole number that divides into each one of them and must be 1. Very possibly, you meant the least common multiple, however?
Answer: None, it is impossible. No single number has a greatest common factor. A "common factor" is a factor that two or more numbers have in common. The "greatest common factor" is the largest factor that two or more numbers have in common.
That's the greatest common factor, or GCF.
The greatest factor of any number is the number itself. There is no integer that is the greatest factor of every number. One is a factor of every number. One is the GCF of co-prime numbers.
In math, the greatest common factor (GCF) of two or more non-zero integers is the largest positive integer that divides the numbers without a remainder.
The greatest common factor of 4225 and 32 is 1
That is correct.
That's called the greatest common factor, or GCF.
That's called the greatest common factor, or GCF.
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor is the largest factor common to two or more numbers.
