请问 non-factorizing 是啥意思?

比如17和69没有公约数（1除外），就叫 non-factorizing.
难道是无公约数的意思？请大侠指正！谢谢！

应该是类似于无法分解
根据维基百科，factorizing 意思类似于因式分解（比此含义广一些）：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).

谢谢！我理解如下：
Like 35 and 19 can not be factorized, which means non-factorizing.
For 38 and 74 can be factorized into 2*19 and 2*37, which means factorizing.

你理解的没错，但是它除了你理解的，还有例如不能因式分解的意思
