請問 non-factorizing 是啥意思?

qdtruck

比如17和69沒有公約數(shù)（1除外），就叫 non-factorizing.  
3 L! Z( ~: d, j- N/ I, }- j難道是無公約數(shù)的意思？請大俠指正！謝謝！

8 T; u3 ~+ @1 N) F* K根據(jù)維基百科，factorizing 意思類似于因式分解（比此含義廣一些）：In mathematics, factorization (also factorisation in some forms of British English) or factoring is the decomposition of an object (for example, a number, a polynomial, or a matrix) into a product of other objects, or factors, which when multiplied together give the original. For example, the number 15 factors into primes as 3 × 5, and the polynomial x2 − 4 factors as (x − 2)(x + 2).

你理解的沒錯，但是它除了你理解的，還有例如不能因式分解的意思
