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

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...
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 factors are 1 and the number itself are called Prime Numbers“. Therefore we can state the fact that 1 is not a ...
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...
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...
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 ...

The prime number and composite number identification teaching aid consists of a cubic hollow transparent box, a baffle and balls, wherein the upper and lower sides of the cubic hollow transparent box are provided with slideways; the baffle which can move along the slideways is arranged in the ...
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...
