To find the highest common factor of two numbers you first need to break them down into their prime factors. In this case:
24 = 2x2x2x3
28 = 2x2x7
The next step is to identify the common factors. In this case, both numbers have two 2s as a factor. We multiply these together to get the HCF:
2x2=4
Thus 4 is the highest common factor of 24 and 28.
The greatest common factor of 20, 28, and 24 is 4.
It is: 4
The GCF is 14.
The Highest Common Factor is 14
Since 28 is a factor of 84, it is automatically the GCF.
The highest common factor is 7.
The highest common factor of the numbers 28, 84 and 91 is 7.
The least common prime factor of 24 and 28 is 2.
The highest common factor (HCF) is 7.
The highest common factor is 4.
4 is the highest common factor of 28 and 32
The GCF is 28.
The Greatest Common Factor (GCF) is: 28
1 and the highest common factor is 4
The greatest common factor of 20, 28, and 24 is 4.
Common factors of 24 and 28 are: 1, 2, and 4.
it is 7
