Im not actually at high school, im at college but i felt this is at high school level. I'm doing a Web Development degree at uni next work and need to brush up on my algebra.
First of all i understand how to do Prime Factorization with integers, eg: Find PF of 459:
What about when working with floating point (decimal)? Does PF Only work with integers?
459 = 3 x 3 x 3 x 17 (dont know how to right exponents on this forum)
Also last question, is it appropriate to use a calculator when trying to find the PF on a number? Without a calculator the process takes a while, when doing exams would i be expected to use a calculator when trying to find the PF of a number with more then 5 digits?
