What is the GCF of 28 20 and 40?

To find the GCF, you first need to break the numbers down into their prime factors: 28 = 2x2x7 20 = 2x2x5 40 = 2x2x2x5 The next step is to find any common prime factors. In this case, all three numbers have two 2s as prime factors. Multiply these and you get 4. Therefore the GCF of 28, 20 and 40 is 4.

What is the highest common factor of 28 32?

To find the highest common factor of two numbers, you must first split them into their prime factors. In this case, the numbers 28 and 32 can split as follows: 28 = 2x2x7 32 = 2x2x2x2x2 The next step is to identify all common prime factors. In this case, the common prime factors are two 2s. To find the HCF, you just multiply these together: 2x2=4 Thus the highest common factor of 28 and 32 is 4.
