30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, ...
360, 420 and 480 all have 24 factors.
Prime factorization of 270: 2x3x3x3x5 So any one of these factors or combination of these factors will divide exactly into 270. Any number that is not one of these factors or a combination will not. For example, 3x3x3x2=54 so 54 will divide exactly into 270. 270/54 = 5
