what is the highest common factor of 16 and 24

Question

i also need the lists 

 

Answer 1

The factors of 16:   1, 2, 4, 8, 16

    Note: these are formed by selecting some of  1*2*2*2*2

 

The factors of 24:   1, 2, 3, 4, 6, 8, 12

    Note: these are formed by selecting some of 1*2*2*2*3

 

The Greatest Common Factor (GCF) of 16 and 24 is 8.    [It is the largest number in both lists.]

   It is also the largest grouping of factors that are in both groupings --    2*2*2

Answer 2

Using prime factorization gives us:

 

16 = 2 x 8 = 2 x (2 x 4) = 2 x 2 x 2 x 2

 

24 = 3 x 8 = 3 x (2 x 4) = 3 x (2 x 2 x 2) = 2 x 2 x 2 x 3

 

What is the greatest common factor that these two share, Muna?
