GMAT考试必看数学算数知识点：整数

对于GMAT考试的数学部分的备考来说，同学们需要通过大量的真题练习才能夯实基础，不断的掌握知识点以及一些难题的解题方法小编在坦途网GAMT考试频道还有很多相关的内容和考试资讯，下面就是小编为大家整理的详细内容，供大家参考！

一.整数：integer，whole number 因子：factor or divisor

If x and y are integers and x≠0,x is a divisor (factor) of y provided that y=xn for some integer n. In this case y is also said to be divisible by x or to be a multiple of x. For example, 7 is a divisor or factor of 28 since 28=7·4, but 8 is not a divisor of 28 since there is no integer n such that 28=8n.Divisible adj.可以被整除的　　multiple　n.倍数

2.商和余数：quotients and remainders

余数和商都可以为0

3.奇数和偶数：odd and even integers

奇数和偶数都可以是负数;零一定是偶数

4.质数和合数：prime numbers and composite numbers

A prime number is a positive integer that has exactly two different positive divisors，1 and itself. For example, 2,3,5,7,11, and 13 are prime numbers, but 15 is not, since 15 has four different positive divisors, 1, 3, 5, and 15. The number 1 is not a prime number, since it has only one positive divisor. Every integer greater than 1 is either prime or can be uniquely expressed as a product of prime factors. For example, 14= (2) (7), 81= (3) (3) (3) (3), and 484= (2) (2) (11) (11).

注:除了1和其本身外,还有其他因子的数叫合数。最小的质数为2，最小的合数为4，在讨论质数和合数时，都指正数。1和0既不是质数，也不是合数。
