I suggested a feature for this yesterday: https://github.com/stackernews/stacker.news/issues/1422

= 5×2×3×3×2×2×2×7×3×2×5×2×2×3×2×1

= 7×5×5×3×3×3×3×2×2×2×2×2×2×2×2×1

[Daily puzzle] If m! x n! = 10! then m x n = ?

10! = 10×9×8×7×6×5×4×3×2×1
= 5×2×3×3×2×2×2×7×3×2×5×2×2×3×2×1
= 7×5×5×3×3×3×3×2×2×2×2×2×2×2×2×1
So either m or n must be >= 7 
= 7!×5×3×3×2×2×2×2×1
= 7! ×6×5×4×3×2×1
= 7!×6!
m=7, n=6
m×n=42
