When the only two factors of a number are 1 and the number, then it is a Prime NumberIt means the same as our previous definition, just stated using factors.And remember this is only about Whole Numbers (1, 2, 3, ... etc), not fractions or negative numbers. So don't say "I ...
prime number = 质数 质数又称素数.指在一个大于1的自然数中,除了1和此整数自身外,没法被其他自然数整除的数.换句话说,只有两个正因数(1和自己)的自然数即为素数.composite number= 和数比1大但不是素数的数称为合数.1和0既非素数也非合数.合数是由若干个质数相乘而得到的.所以,质数是合数的基础,没有质数...
Illustrated definition of Prime Number: A whole number above 1 that can not be made by multiplying other whole numbers. Example: 5 is a prime...
The number one is neither composite nor prime. Let us study in detail about 1 as a prime number with examples. Is 1 a Prime Number? The answer to the question ‘why 1 is not a prime number’ lies in the definition of prime numbers i.e. is “The numbers other than 1 whose only ...
Prime number：质数，又称素数，指在大於1的自然数中，除了1和该数自身外，无法被其他自然数整除的数（也可定义为只有1与该数本身两个因数的数）。例如，5是个质数，因为其正因数只有1与5，而6则是个合数，因为除了1与6外，2与3也是其正因数。算术基本定理确立了质数於数论里的核心地位：任何大...
Definition #2: A number is prime if the number has only 2 factors, 1 and itself.If the number has more than two factors, we say that the number is composite.For instance, 12 is a composite number because 12 has more than 2 factors. It can be divided by numbers other than 1 and ...
Prime Number和Composite Number的解释如下：一、Prime Number 质数是指一个大于1的自然数，除了1和它本身以外不再有其他因数的数。例如，2、3、5、7、11等都是质数。二、Composite Number 合数是指除了能被1和它本身整除以外，还能被其他数整除的大于1的自然数。简单来说，一个合数至少可以被除1和...

A prime number has exactly two distinct positive divisors: 1 and itself. A composite number has more than two distinct positive divisors. 定义区分质数和合数主要依据因数的数量:1. 质数:必须满足两个条件: - 大于1的自然数 - 仅有1和自身两个因数 - 示例:2(唯一偶质数)、3、5、7... - 如果n≤...
质数（prime number）又称素数，有无限个。除了1和它本身以外不再有其他的除数整除。根据算术基本定理，每一个比1大的整数，要么本身是一个质数，要么可以写成一系列质数的乘积，最小的质数是2。【Composite number】an integer exactly divisible by at least one number other than itself or 1.合数...
