4 does not.
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
whenever you start the factor tree always divide by the lowest number possible first... 2 * 5 * 3 * 3 * 3 = 270 2 = 2 5 = 5 9 = 3 * 3 * 3
93.3 90 ) 839.7 ------------- 810 297 270 270 0 to explain you try to divide 90 into 8 won't go divided 90 into 83 won't go divide 90 into 839 goes 9 times remainder 29 drop the last 7 to the 29 to make 297 90 goes into 297 3 times remainder 27 drop 0 to the 27 to make 270 90 goes into 270 3 times
