It is defined as the ratio of the likelihood of one particular hypothesis to the likelihood of another hypothesis. Typically, it is used to find the ratio of the likelihood of an alternative hypothesis to a null hypothesis. The Bayes factor is calculated as the likelihood of data given the alternative hypothesis divided by the likelihood of data given the null hypothesis.2 Sources

Bayes factor - Wikipedia
The Bayes factor is the ratio of two marginal likelihoods; that is, the likelihoods of two statistical models integrated over the prior probabilities of their parameters. The posterior probability $${\displaystyle \Pr(M|D)}$$ of a model M given data D is given by Bayes' theorem: See more
The Bayes factor is a ratio of two competing statistical models represented by their evidence, and is used to quantify the support for one model over the other. The models in question can have a common set of parameters, … See more
