What isn't the longest factor string for 210?

The longest factor string for 210 is not simply the factors multiplied together in a straightforward manner, such as (2 \times 3 \times 5 \times 7). Instead, it can involve breaking down these factors into smaller integers that multiply to 210, like (1 \times 2 \times 3 \times 5 \times 7) or any combination of these factors that maintain the product of 210. Therefore, a string that doesn't maximize the count of factors, such as (1 \times 210), is not the longest factor string.
