2024 AIME I Problem 8

Eight circles of radius 34 can be placed tangent to \overline{BC} of \triangle ABC so that the circles are sequentially tangent to each other, with the first circle being tangent to \overline{AB} and the last circle being tangent to \overline{AC}, as shown. Similarly, 2024 circles of radius 1 can be placed tangent to \overline{BC} in the same manner. The inradius of \triangle ABC can be expressed as \frac{m}{n}, where m and n are relatively prime positive integers. Find m + n.

Leading zeroes must be inputted, so if your answer is 34, then input 034
