Answer :

a factor of 24 is a number that can be multilied by another number (normally whole (not fraction or decimal) numbers)

so a factor must be less than the number

any multiple of 2 greater than 24 will work so
just any even number greater than 24 exg 26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60, and so on
