比如17和69沒有公約數(shù)(1除外),就叫 non-factorizing.

應該是類似于 無法分解4 _( z0 c! O+ ^! m) {! l- d
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).4 }8 f- p7 N: K( d) g
