WebThe number 1 is called the unit, and it is clear that 1 is a divisor of every positive integer. If c can be expressed as a product ab in which a and b are positive integers each greater than 1, then c is called composite. A positive integer neither 1 nor composite is called a prime number. Thus, 2, 3, 5, 7, 11, 13, 17, 19, … are prime numbers. WebUsually when people want to count divisors, they just count the positive ones. If you want to also count the negative ones, then multiple the number of positive divisors by 2. 600 = 2 3 ⋅ 3 ⋅ 5 2. So any divisor of 600 will be of the form 2 a ⋅ 3 b ⋅ 5 c where 0 ≤ a ≤ 3, 0 ≤ b ≤ 1, and 0 ≤ c ≤ 2. But -2, - 1, -10 and so on ...
