To perform prime factorization or to find factors of any number say 15. Enter ifactor(15) then press Enter. Answer 3 * 5 will be displayed. Work Shown: 15 is divisible by 3: 15 = 5 * 3. ifactors decomposes the integer (or the integers of the list) into prime factors,but the result is given as a list (or a list of lists) in which each prime factor is followed by its multiplicity.

HP Prime CAS HP Prime uses the Giac/Xcas Version 1.1 Engine. Giac/Xcas is an open source CAS (Computer Algebra System) project initiated by Bernard Parisse from Institut Fourier (University of Grenoble I, France). Giac is a C++ library that has types for symbolic algebraic manipulations. Xcas is a GUI (Graphical User Interface) linked with Giac that provides the functionalities of a general purpose CAS. Project Background: The Giac/Xcas project began in year 2000, following the development of the CAS for HP graphing calculators.

What are Prime Numbers? A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because only 1 and 5 evenly divide it, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6.

GCF or Greatest Common Factor Entering gcd(Number1, Number2) will return the greatest common divisor of the two numeric values. The lcm function wull only accepts two values at a time. Example: Find the GCF (or GCD) for 12, 24, and 32. Press [ CAS] key Enter gcd(12,24) and press [Enter] key. It should display the result of 12. Enter gcd(12,32) and press [Enter] key. It should display the final result of 4.

LCM or Least Common Multiple Entering lcm(Number1, Number2) will return the least common multiple of the two numeric values. The lcm function will only accepts two values at a time. Example: Find the LCM for 10, 15, and 45. Press [ CAS] key Enter lcm(10,15) and press [Enter] key. It should display the result of 30. Enter lcm(30,45) and press [Enter] key. It should display the final result of 90.

To perform prime factorization or to find factors of any number say 15. Enter 15 press = Press [Blue Shift] key followed by [FACT] key. Answer 3x5 will be displayed. Work Shown: 15 is divisible by 3: 15 = 5 * 3.
