' 1 ' and ' 3 ' both do. They're called the "common factors" of 87 and 33 .
Since the sum of the proper factors of 87 is only 33, 87 is not an abundant number.
1, 3, 29, 87
3 goes into 33 and 39
11/33
The number 3 goes into both 6 and 33 (6/3 = 2, 33/3 = 11)
33*9=273*11=33
87 * 33 = 2610 + 261 = 2871 ■
There are four: 1, 3, 11 and 33
Not sure what you mean but 87 goes into 174 twice. Of course this means 2 goes into 174 87 times. 6 goes into it 29 times.
The number 1.
The highest common factor of 87 and 33 is 3. 87 = 3 x 29 33 = 3 x 11
14/33 cannot be simplified as no number that goes into 14 also goes into 33
