The greatest common factor of 15, 20, and 25 is 5.

The HCF (Highest Common Factor) of 15, 20, and 25, can be easily determined, since all of the values end in 0 or 5, therefore, each of them are divisible by 5. 15/5 = 3, 20/5 = 4, and 25/5 = 5, which 3 and 5 are prime. Therefore, 5 is the GCF (HCF) of 15, 20, and 25.
