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.
The GCF is 21.

The GCF is 18.
The GCF is 252.
7 is the greatest common factor; it divides evenly into all of the numbers.

The GCF is 14.hcf(42, 56, 98) = 1442 = 2 x 3 x 756 = 23 x 798 = 2 x 72hcf = 2 x 7 = 14
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
You need at least two numbers to find a GCF. If that's 7 and 56, the GCF is 7.
The GCF is 252.
7 is the greatest common factor; it divides evenly into all of the numbers.
The best way to figure this problem out is to find out all of the factors of the smaller number, which is 90. Start with the highest factor of 90 and work your way down until you find a number that goes into 756. Here is the answer. The factors of 90 are 1,2,3,5,6,9,10,15,18,30,45,90 90 does not go into 756. 45 does not go into 756. 30 does not go into 756. 18 goes into 756, so the answer is 18.

The greatest common factor must be a factor of the smallest number. The smallest number is 7. Its factors are 1 and 7. So the greatest common factor must be either 1 or 7. Since 7 is the larger of the two factors, check whether it is a factor of the additional numbers. Since it is, 7 is the greatest common factor.
