比如17和69没有公约数(1除外),就叫 non-factorizing.  
# e' h9 Y' c4 d4 t, Q3 \& t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6 M) p9 A9 n" m& `4 a
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).

Like 35 and 19 can not be factorized, which means non-factorizing.7 Q1 D, r- \# _2 s8 i- o
For 38 and 74 can be factorized into 2*19 and 2*37, which means factorizing.
