To determine which numbers in the list are divisible by 3, we need to check if the sum of their digits is divisible by 3. If the sum of the digits is divisible by 3, then the number itself is also divisible by 3.
Here is the list with the sums of the digits of each number and whether or not they are divisible by 3:
- 175 (sum = 1+7+5 = 13) [Not divisible by 3]
- 825 (sum = 8+2+5 = 15) [Divisible by 3]
- 324 (sum = 3+2+4 = 9) [Divisible by 3]
- 960 (sum = 9+6+0 = 15) [Divisible by 3]
- 320 (sum = 3+2+0 = 5) [Not divisible by 3]
- 2376 (sum = 2+3+7+6 = 18) [Divisible by 3]
- 3969 (sum = 3+9+6+9 = 27) [Divisible by 3]
- 1902 (sum = 1+9+0+2 = 12) [Divisible by 3]
- 3111 (sum = 3+1+1+1 = 6) [Divisible by 3]
- 824 (sum = 8+2+4 = 14) [Not divisible by 3]
- 2984 (sum = 2+9+8+4 = 23) [Not divisible by 3]
- 607 (sum = 6+0+7 = 13) [Not divisible by 3]
- 14168 (sum = 1+4+1+6+8 = 20) [Not divisible by 3]
Numbers from the list divisible by 3 are: 825, 324, 960, 2376, 3969, 1902, and 3111.
