4a2+ 25 does not factor over the real number field. In the complex numbers , it
factors as (2a +5i)(2a - 5i).
This is because i2 = -1, so 4a2 + 25 = 4a2 - (- 25) = 4a2 - 25(-1) = 4a2 - 25i2

What is the greatest common factor of 10 20 25?
25 is not a multiple of 10, so the greatest common factor would not be 10. A lower common factor would be 5, because 10, 20 and 25 all divide by 5, so 5 is the greatest common factor of 10, 20 and 25.
