Examples

1、Zero is neither a positive number nor a negative number. Zero is the least natural number.

零既不是正数也不是负数。零是最小的自然数。

2、Among all the factors of an integer, the least is 1 and the greatest is the integer itself.

一个整数所有的因数中，最小的因数是1，最大的因数是它本身。

3、Integer a is divided by integer b without a remainder and the quotient is also an integer. That is to say integer a can be divided exactly by integer b or integer b can divide integer a exactly.

整数a 除以整数b，如果所得的商仍是整数而余数为0，那么我们就说a能被b整除，或者说b能整除a。

4、If integer a can be divided exactly by integer b, a is called the multiple of b and b is called the factor of a.

如果整数a能被整数b整除，那么a就称之为b的倍数，b就称之为a的因数。

5、An even number is an integer that is divided by 2 without a remainder. An odd number is an integer that is not divisible by 2.

能被2整除的整数叫偶数，不能被2整除的整数叫奇数。

6、A prime number (or a prime) is a natural number that has exactly two distinct natural number factors, one and itself.

如果一个自然数只有1和它本身两个因数，那么我们称这个自然数为素数（或 质数）。

7、A composite number is a positive integer which has a positive divisor besides 1 and itself.

如果一个正整数除了1和它本身还有其它的因数，那么我们称这个正整数为合数。

8、If two integers have only one common factor 1, they are coprime.

如果两个整数的公因数为1，那么这两个数互素。
