PrimeFactors( <Number> )
Returns the list of primes whose product is equal to the given number.
Examples:
  • PrimeFactors(1024) yields {2, 2, 2, 2, 2, 2, 2, 2, 2, 2}.
  • PrimeFactors(42) yields {2, 3, 7}.

CAS Syntax

PrimeFactors( <Number> )
Returns the list of primes whose product is equal to the given number.
Examples:
  • PrimeFactors(1024) yields {2, 2, 2, 2, 2, 2, 2, 2, 2, 2}.
  • PrimeFactors(42) yields {2, 3, 7}.
