Itself and any of its factors will divide evenly into -72 with no remainders.
Suppose it is x. Then 72/x = 30% = 30/100 So x = 72*100/30 = 720/3 = 240
72 divided by 40 is 1% so 100 times that is...
Well, honey, let me break it down for you. The numbers that can evenly divide into 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. So, grab a calculator or use that brain of yours to do the math, and you'll see that these numbers will fit perfectly into 72 without any leftovers.
2, 4
Only the number one.
1, 2, 3, 4, 6, 12.
2.
Itself and any of its factors will divide evenly into -72 with no remainders.
1 and 3.
3
The number is 24.
Itself and any of its factors
72/36 = 2
1, 3 and 9 will go into both numbers evenly
72 and 100 is divisible by 2.
