# C548 — Chronological and census quantities meet through scalar factorization

## Question

What does the supplied579600 factorization add to the construction grammar?

## Inputs

```json
{
  "imported_File59_scalar": 579600,
  "chronological_spine": 161,
  "macro_factors": [
    1260,
    460
  ],
  "P": "70/69"
}
```

## Sources

```json
[
  "File60 §§1,8.1,10; File59 provenance imported through File60"
]
```

## Results

```json
{
  "factorizations": [
    579600,
    579600
  ],
  "P_scalar": 588000,
  "expanded_factorizations": [
    588000,
    588000,
    588000
  ],
  "operation_type": "typed numerical product/refactorization of imported census scalar; not a calendar conversion of people into years"
}
```

## Finding

The same579600 factors through161 or1260×460 and expands under P to588000. Products and quotients belong in an explicit scalar-comparison layer alongside the chronological maps. The arithmetic is reconstructed; File59’s underlying census derivation is not re-audited here.

## Reassessment

Connect the458640 census comparison to the already established common calendar measure.

## Checks

```json
{
  "macro": true,
  "P": true,
  "factors": true
}
