Well, isn't that a happy little question! To find the Highest Common Factor (HCF) of 315 and 660, we look for the largest number that divides evenly into both. First, we can find the factors of each number and then identify the highest one they have in common. It's like finding a common color in two beautiful paintings, bringing them together in harmony.

The first step is to express these numbers as products of their prime factors:

315 = 3x3x5x7

660 = 2x2x3x5x11

The next step is to identify any common prime factors. In this case the common prime factors are 3 and 5. Multiply these and you get:

3x5 = 15

Thus the HCF of 315 and 660 is 15.
