On natural numbers, (aRb) if (a) and (b) have the same number of prime factors, counted with repetition. What type of relation is this?

Answer and explanation

Correct answer: Equivalence relation

Step 1: Every number has the same count of prime factors as itself, so reflexivity holds. Step 2: Equality of counts remains true when the order is reversed. Step 3: If two counts are equal through a third number, then the first and third counts are also equal.
