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.  
$ J; E( \- v4 A  L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: Y* a7 s0 [/ ?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).

謝謝！我理解如下：
