# Factor Calculator

> Find all factors, factor pairs, and prime factorization of any positive integer.

## What does this tool do?

The Factor Calculator takes a positive integer and computes:

1. **All factors** — every number that divides evenly into the input, listed in ascending order.
2. **Factor pairs** — pairs (a, b) where a × b = n, listed with a ≤ b.
3. **Prime factorization** — the input expressed as a product of prime powers (e.g. 60 = 2² × 3 × 5).
4. **Factor count** — total number of divisors.
5. **Sum of factors** — sum of all divisors.
6. **Primality** — whether the number is prime.

Results update instantly as you type.

## Examples

| Input | Factors | Factor Pairs | Prime Factorization | Count | Sum | Prime? |
|-------|---------|--------------|---------------------|-------|-----|--------|
| 60 | 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 | (1, 60), (2, 30), (3, 20), (4, 15), (5, 12), (6, 10) | 2² × 3 × 5 | 12 | 168 | No |
| 7 | 1, 7 | (1, 7) | 7 | 2 | 8 | Yes |
| 12 | 1, 2, 3, 4, 6, 12 | (1, 12), (2, 6), (3, 4) | 2² × 3 | 6 | 28 | No |
| 1 | 1 | (1, 1) | (none) | 1 | 1 | No |
