MATHS MAD [file: Factorise] There is a great deal of interest in mathematical functions in computing and W.E. Thomson sent us this routine to factorise numbers (maths students everywhere take note!). There is a time delay which depends on the complexity of the number, the prime 4294967291 will take around 8 minutes to check, most other numbers far less! Note the use of the subroutine at 300, it prints all the digits of a nine or ten character integer unlike the built in PRINT command which rounds off at 8 digits.
