You need at least two numbers to find a GCF. If that's 7 and 56, the GCF is 7.
There's no such thing as the highest 'common' factor of a single number.
"Common" means "same for both".
7The highest common factor is 7
The highest common factor for 18 and 16 is 2.
HCF stands for Highest Common Factor. It is also known as the GCF, or Greatest Common Factor.
The highest or greatest common factor of 420 and 294 is 42.
Highest common factor of 273 and 315 is 21.
The GCF is 18.
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 756 and 19600 is 28
The GCF is 252.
The highest common is 2
Highest common factor is 7.
The Highest Common Factor is: 4
The Highest Common Factor is: 9
The highest common factor is: 20
The highest common factor is 7.
The highest common factor is 35.
The highest common factor is 7.
HCF(735, 756) = 21 It can save you a lot of time if you use the fact that for any integers A and B, HCF(A, B) = HCF(A, B-A) That soon gives you small numbers to factorise.
