The smallest five-digit number divisible by 216 is 10152.
To find this, we need to determine the smallest five-digit number (which is 10000) and then find the first multiple of 216 that is greater than or equal to 10000.
Here's the process:
-
Divide the smallest five-digit number by 216: 10000 / 216 ≈ 46.296
-
Round up to the next whole number: Since we need a whole number multiple, we round 46.296 up to 47.
-
Multiply 216 by the rounded-up number: 216 * 47 = 10152
Therefore, 10152 is the smallest five-digit number divisible by 216.
