multiple vs multiplier - Is it sometimes interchangeably used?

[Seeking truth]

Hello,

I have this sentence when viewing a valuation report. It says,

This can be done either by using a discounted cash flow approach or by applying a multiple derived from the market to a maintainable profit figure.

Somehow, I feel "multiple" is better changed to "multiplier"? Am I right or right?
Is it possible that the world "multiple" here is misused?

I find an explanation of the two words' difference.

"
Multiplier is a related term of multiple.

As nouns the difference between multiplier and multiple
is thatmultiplier is (arithmetic) a number by which another (the multiplicand) is to be multiplied while multiple is (mathematics) a number that may be divided by another number with no remainder. "

From the context, I think "multiplier" fits here better? Am I right? Besides, in this report, the writer repeatively used this word "multiple" in similar usages.

I'm not sure how common it is in accounting to use "multiple" in this way, but it certainly looks wrong from a mathematical perspective. I would use "multiplier".

I think I must have seen it often enough not to be surprised at its use here. To me, you you are right; it is wrong and should be multiplier. Possibly it is AmE usage.
