You need at least two numbers to find a GCF. The good news is 73 is prime so any number you compare it with, if it's not a multiple of 73, the GCF will be one.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 16 and 73 is 1


What is the greatest common factor of 29 and 73?

The greatest common factor of a prime number & a composite number is 1 if the composite number is not divisible by the prime number. 81(composite number) is not divisible by 29(prime number) so, gcf(29,81) = 1.


What is the greatest common factor of 306 and 459?

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 145, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 145 are 1, 5, 29, and 145. Examples: The common factors of 30 and 145 are 1 and 5; the greatest common factor is 5. The common factors of 145 and 149 are only 1; the greatest common factor is 1. The common factors of 145 and 174 are 1 and 29; the greatest common factor is 29.
