### Show Answer

In Excel, you can use the FLOOR function to find the largest integer less than or equal to a specified number. The FLOOR function takes two arguments. The first argument is the number for which you want to find the largest integer. The second argument, known as “significance,” is optional and represents the multiple to which you want to round down the number. If you omit the significance, Excel will default to rounding down to the nearest integer.

For example, if you have a number like 17.58 in cell A1 and you want to find the largest integer less than or equal to this number, you can use the FLOOR function with a significance of 1, like this: =FLOOR(A1, 1). The result will be 17, which is the largest integer less than or equal to 17.58.

You can customize the significance argument to round down to different multiples. For instance, if you need to round down to the nearest multiple of 5, you can use =FLOOR(A1, 5). In this case, the result would be 15, as it’s the largest multiple of 5 that is less than or equal to 17.58.
