A factorial, in decimal, will generally have a number of trailing zeros. For example
7! = 5040
has 4 digits in total, one trailing zero, and so we can say it has 3 significant digits.

The above factorial has four significant digits since the trailing zero is not to the right of a decimal.

You can say that a factorial has zeros as the least significant digits, like 5040.
