720 = 2^4 * 3^2 * 5

1080 = 2^3 * 3^3 * 5

672 = 2^5 * 3 * 7

So, the largest number that evenly divides all of those is

2^3 * 3 = 24

let me rephrase the question ...

what is the greatest common factor of

720, 1008, and 672 ?

720 = 8*9*10 = 16*3*3*5

1008 = 8*9*14 = 16*3*3*7

672 = 16*3*2*7

so who is common?

looks like 16*3 or 48

check:

720/48 = 15

1008/48 = 21

672/48 = 14 , nothing common in any of those 3 answers.

I misread 1008 as 1080.
