Seven of them.
There are in finitely many of them. The smallest is 432. They are of the form Pa*Qb*Rc where P, Q, R are prime and a, b, c are integers greater than equal to 0 such that (a+1)*(b+1)*(c+1) = 12.
The product of the prime numbers 3 and 5 is 15.
37 = 37. No other number (prime number or otherwise) is equal to 37.
It means they have no common factors. This term is really only useful for integers, preferably positive integers.
It is a prime number.
All integers greater than one are divisible by prime numbers.
Integers greater than one that are not prime are composite.
Prime numbers are integers. They won't equal a decimal.
All of them.
All numbers greater than one are positive integers that are either composite or prime numbers.
They are in the subset of integers which are greater than 1.
Integers greater than 1, that are not prime numbers, are called composite numbers, because they are "made up of" more than one prime factor.
There are 80 such integers.
There is no particular characteristic that is common to such numbers other than they are positive integers greater than or equal to 4.
No. Odd numbers can be greater than, smaller than, or equal to prime numbers.
Set builder notation for prime numbers would use a qualifying condition as follows. The set of all x's and y's that exist in Integers greater than 1, such that x/y is equal to x or 1.
All the even numbers greater than 2 are composite.
