A perfect number is one where all its smaller friends add up to it. For example, the number 6 has friends 1, 2, and 3, when you add them together (1 + 2 + 3), you get exactly 6! That’s what makes it a perfect number. It's like having a group of friends who always give you the exact amount you need, no more, no less.
Examples
- The number 6 is perfect because its friends 1, 2, and 3 add up to it.
- 28 has smaller friends like 1, 2, 4, 7, and 14, which together sum to 28.
