Identify a number that is divisible by 17, 3 , and 9,which is not divisible by 7, 18, 5, 16, and 14. Describe how u found this number.
~PLEASE help me. :)
17*3*9=459
459/7=65.57
459/18=25.5
459/5=91.8
459/16=28.68
459/14=32.78
However it is divisible by
459/17=27
459/3=153
459/9=51
thx soo soo soo very much!
To find a number that is divisible by 17, 3, and 9 but not divisible by 7, 18, 5, 16, and 14, we can follow these steps:
1. Start with the number 1 and increment it by 1 until we find a number that meets the criteria.
2. To determine if a number is divisible by 17, we divide it by 17 and check if the remainder is 0. If the remainder is 0, then the number is divisible by 17.
3. To determine if a number is divisible by 3, we add up all the digits in the number. If the sum is divisible by 3, then the number is divisible by 3.
4. To determine if a number is divisible by 9, we follow the same procedure as step 3 but check if the sum is divisible by 9.
5. To check if a number is not divisible by 7, 18, 5, 16, and 14, we divide the number by each of these numbers and ensure the remainder is not 0.
Using this approach, let's find a suitable number:
Start with 1: Not divisible by 17, 3, or 9.
2: Not divisible by 17, 3, or 9.
3: Not divisible by 17.
4: Not divisible by 17, 3, or 9.
5: Not divisible by 17 or 9.
6: Not divisible by 17, 3, or 9.
7: Not divisible by 3 or 9.
8: Not divisible by 17, 3, or 9.
9: Divisible by 3 and 9, but not divisible by 17.
10: Not divisible by 17, 3, or 9.
11: Not divisible by 17.
12: Divisible by 3, but not divisible by 17 or 9.
13: Not divisible by 17, 3, or 9.
14: Not divisible by 3.
15: Not divisible by 17, 3, or 9.
16: Not divisible by 17.
17: Divisible by 17, 3, and 9 but not divisible by 7, 18, 5, 16, or 14.
Therefore, the number we found is 17.
Please note that there might be other numbers that meet the given criteria, and this is one example of such a number.
