- First factorize 2880 i.e, (2^6)*(5)*(3^2). So if we divide this by 5, we get 576 and it is a perfect square for 24.
So, 5 is the answer. - 9 years agoHelpfull: Yes(1) No(0)

- 5 will be the ans
factors of 2880=4*4*4*9*5
if 2880 is divided by 5 then it will be equal to 4*4*4*9 which is perfect square.
