less tangible factors vs fewer tangible factors

[vectra]

Hello,

This is a paragraph from a model answer for IELTS Task 2 Writing:

'The measure of success is a subjective issue that some argue is represented by having both money and being successful in one’s profession. However, there are many less tangible factors that are better indications of success, as will now be argued.'
The topic under the discussion is 'The mark of a successful person is to be wealthy and have a successful career.'

I am not sure about the 'less tangible factors' part.
Knowing that IELTS is a formal examination, and this is not the Speaking part of it, is it possible to use 'fewer tangible factors' instead of 'less tangible factors'?

Thank you in advance.

No. The factors are "less tangible" and there are many of them. It's not saying that there are fewer tangible factors. It is saying that there are many factors which are "less tangible" than having money and being successful.
