Answer:
39,960 is divisible by all of the listed numbers.
Step-by-step explanation:
The sum of digits is 3+9+9+6+0 = 27, and the sum of those digits is 2+7=9.
This tells you the number is divisible by 3 and 9.
The number is even and ends in 0. Together with divisibility by 3, this tells you the number is divisible by 6. The 0-ending tells you the number is divisible by 2 and 5 and 10.
The last two digits are 60, a number that is divisible by 4, so the number is divisible by 4.
39,960 is divisible by all of the numbers listed: 2, 3, 4, 5, 6, 9, 10.
