To check if a number is divisible by 24, we need to ensure it is divisible by both 3 and 8.
1. 3125736:
Divisibility by 3: Sum of digits = 3 + 1 + 2 + 5 + 7 + 3 + 6 = 27, which is divisible by 3.
Divisibility by 8: The last three digits are 736, which is divisible by 8.
2. 35718:
Divisibility by 3: Sum of digits = 3 + 5 + 7 + 1 + 8 = 24, which is divisible by 3.
Divisibility by 8: The last three digits are 718, which is not divisible by 8.
3. 537804:
Divisibility by 3: Sum of digits = 5 + 3 + 7 + 8 + 0 + 4 = 27, which is divisible by 3.
Divisibility by 8: The last three digits are 804, which is not divisible by 8.
4. 63810:
Divisibility by 3: Sum of digits = 6 + 3 + 8 + 1 + 0 = 18, which is divisible by 3.
Divisibility by 8: The last three digits are 810, which is not divisible by 8.
Based on the analysis, only the number 3125736 is divisible by both 3 and 8, so it is exactly divisible by 24.
∴ The number is exactly divisible by 24 is 3125736.
