Answer: Heyaa!~

                  - Write 63 as the product of prime factors -

  • Since, the prime factors of 63 are 3, 7. Therefore, the product of prime factors = 3 × 7 = 21.

              - Write the prime factors in ascending order -

  •                      I think it would be 3/7

         -   what's the highest common factor of 63 and 105   -

  •                 21,  divides both 63 and 105, i.e., 21.

             Hopefully this helps you! ^^^
