請問 non-factorizing 是啥意思?

qdtruck

比如17和69沒有公約數（1除外），就叫 non-factorizing.  
; s. Q8 s. V. ^+ P1 R/ X7 Q難道是無公約數的意思？請大俠指正！謝謝！

一點一點來

應該是類似于 無法分解
# z( n: s$ L4 ?根據維基百科，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
