Webof 8 and 24 are 1, 2, 4 and 8 since 1, 2, 4 and 8 are factors of both 8 and 24. The highest common factor (HCF) is the largest number that divides into two or more terms. Hence, the HCF of 8 and 24 is 8, as explained in Chapter 1. When two or more terms in an algebraic expression contain a common factor, then this factor can be shown outside of a bracket.
