(11 x 4) + (10 x 4) = 21 x 4 = 84
Greatest Common Factor is GCF
W(1 + 1)
highest common factor
If you divide the product of two given numbers by their GCF, the result will be their LCM.
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.
The same as the product of 84 and 90.
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.
1056
54
1 is the only common factor of 3 and 4. 12 is the least common product of 3 and 4.
That's the Greatest Common Factor, or GCF.
