Greatest Common Factor is GCF
highest common factor
Impossible to answer ! You need another number to compare it with - hence the phrase '...greatest common factor...'
Divisor is another word for factor. Common divisors are often called common factors, in fact the term GCD or greatest common divisor is the same as GCF which is greatest common factor.
You can multiply 2 x 7 (their common prime factors) to get 14, the GCF.
Prime factor each number and then multiply all the common factors to get the GCF.120=2x2x2x3x5240=2x2x2x2x3x52x2x2x3x5=120 is the Greatest Common Factor
In order to have a "greatest common factor" you need to have more than one number, so that 175 has factor in common with another number.
No, 4 is the greatest common factor of those numbers. Multiples are larger.
There is none, it continues to multiply and go on and on.
To get the greatest common factor you must multiply the two numbers together, in this case giving you 156.
if you mean greatest COMMON then it it 9. if you mean any factor those numbers have then its themselves because you multiply them by 1.
Factor each to primes then, choose the common primes to multiply.56=2x2x2x781=3x3x3x3Greatest common is the multiplication identity 1.
