You cannot find an impact factor for the journal “Arabian Journal of Business and Management Review (Oman Chapter)” simply because they don’t have one. A journal only gets an impact factor assigned when indexed in Clarivate’s SCIE/SSCI or ESCI and whether a journal is indexed can be checked here https://mjl.clarivate.com/home
Even stronger there are numerous red flags that the journal and publisher behind it “Arabian Group of Journals (AGJ)” is predatory:
-The publisher is mentioned in the Beall’s list (https://beallslist.net )
-The indexing info (https://www.arabianjbmr.com/indexing.php ) is full of so-called misleading metrics (https://beallslist.net/misleading-metrics/ ) often used by predatory journals/publishers
-The mentioning of the DOAJ logo is misleading since they are not a member
-The journal titles are a mess take for example https://j.arabianjbmr.com/index.php/kcajbmr and for example https://www.hilarispublisher.com/open-access/yeimpact-of-demographic-profile-on-toothpaste-buying-behaviour-in-bangalore-city-2224-8358-1-101.pdf
-Etc.
Anyway, I am afraid that this is not a good journal (and publisher) and in answer to your question: they definitely have no impact factor.
Predatory publishers like to lure in researchers so that they think their publication will be legitimate. Putting out impact factors from a non-Clarivate is one of these strategies.
I presume that you refer to this site https://exaly.com/journal/91543/oman-chapter-of-arabian-journal-of-business-and-management-review/ where 0.1 as impact factor is mentioned.
Although I checked a number of journals that do have a real impact factor at this site https://exaly.com and conclude that the mentioned impact factors deviate only 0.1-0.5 from the real ones and my impression is that the initiative is quite genuine https://koyauniversity.org/node/348 it is important to realize that as already indicated by Jürgen Weippert the only internationally accepted impact factor is assigned by Clarivate once a journal is indexed in their SCIE/SSCI and ESCI index. Besides the CiteScore as assigned by Scopus all other alternative impact factor kind of metrics are at best not recognised or misleading (see for examples https://beallslist.net/misleading-metrics/ ).
I share the suspicions of Dr Jürgen Weippert that this is one of the ways that journals use to appear more legitimate and attractive to potential authors. I, myself, would more strongly consider journals on this topic (business/management) with impact factors that are more officially recognised and accepted.
