"coprime"音標為[?k?pra?m] ，意思是"成互質數"，即兩個數除了1和它們自身以外沒有其他公因數?；痉g為"互質的"或"成互質的"。

速記技巧：可以嘗試使用以下方法來快速記憶這個詞：

1. 諧音記憶：可以將單詞的發音轉化為中文"扣皮"來記憶，這樣有助于快速記憶單詞讀音。

2. 形象記憶：coprime的字母可以組成一個圖像，即兩個數字并排在一起，彼此互不干擾，就像兩個互質的數一樣。

通過以上技巧，可以更輕松地記住"coprime"這個單詞及其含義。

Coprime這個詞源于拉丁語，意為“互質的”。它的變化形式包括composite（合成的）和improper（不適當的）。相關單詞包括prime（主要的），composite number（合成數），improper fraction（不純分數），and perfect number（完美數）。

Coprime這個詞在數學中用來描述兩個數，它們沒有公共的因子，也就是說，它們是互質的。例如，6和9就是一對coprime數，因為它們沒有公共的因子2或3。這種關系在數學中有著重要的應用，特別是在數論和代數結構的研究中。

Coprime Numbers and Their Applications

Coprime numbers, which are numbers that have no common factors, are an essential part of mathematics and have many applications in various fields. From prime number cryptography to optimization problems, coprime numbers play a crucial role.

In prime number cryptography, coprime prime numbers are used to generate keys that are difficult to decode, making them secure against malicious attacks. In optimization problems, coprime arithmetic can be used to simplify calculations and find optimal solutions more efficiently. Coprime pairs and coprime factorization are also important concepts in mathematical analysis, where they help us understand the structure of numbers and develop new mathematical tools.

Coprime numbers are fascinating because of their simplicity and versatility, and their applications are endless. Understanding and using coprime numbers can help us unlock new possibilities and solve complex problems more effectively.
