2 is for selecting 2 numbers out of 100.25 is divided because we are removing all the prime numbers between 1-100 I.e. 25.99 maybe because we are removing 1 from the list because 1 multipled with any number would result in the same number only and that’d have 2 factors, 1 and itself.I’m a bit unsure about 99 though, if someone can confirm, that’d be great.
