Syntax

(success, e2, e3, e5) = prime235Factorization(n);

Description

Compute the factorization of input Integer n in prime numbers 2, 3, and 5. If this is possible, success = true and e2 is the number of prime numbers2, e3 the number of prime numbers 3 and e5 the number of prime numbers 5. If this is not possible, success = false, and e2, e3, e5 are dummy values.

Example

(success, e2, e3, e5) = prime235Factorization(60)   // success=true, e2=2, e3=1, e5=1 (= 2^2*3^1*5^1)
(success, e2, e3, e5) = prime235Factorization(7)    // success=false

(success, e2, e3, e5) = prime235Factorization(n)

n	Type: Integer

success	Type: Boolean Description: = true, if factorization in 2,3,5 is possible
e2	Type: Integer Description: n = 2^e2*3^e3*5^e5
e3	Type: Integer Description: n = 2^e2*3^e3*5^e5
e5	Type: Integer Description: n = 2^e2*3^e3*5^e5
