Final answer:
To determine if a number is divisible by 2, we check if the last digit is even. To determine if a number is divisible by 3, we add up the digits and see if the sum is divisible by 3. The numbers 1044, 1485, 1620, and 1709 are divisible by different combinations of 2, 3, 5, 6, and 9.
Step-by-step explanation:
To determine if a number is divisible by 2, we check if the last digit is even (0, 2, 4, 6, or 8). To determine if a number is divisible by 3, we add up the digits and see if the sum is divisible by 3. To determine if a number is divisible by 5, we check if the last digit is either 0 or 5. To determine if a number is divisible by 6, we check if it is divisible by both 2 and 3. To determine if a number is divisible by 9, we add up the digits and see if the sum is divisible by 9. To determine if a number is divisible by 10, we check if the last digit is 0.
