This is a new one on us, and as we try to understand whether or not the whole idea
has any meaning, our most urgent question is: Exactly how would the first Prime number
be "made of" the other prime numbers ?
They certainly couldn't be multiplied, because then the big one would have factors,
and it wouldn't be a prime number.
They couldn't be divided, because if you divide one prime number by another one,
the quotient is never a whole number. So that can't be it either.
Could two prime numbers be added to get another one ? Well, all of the prime numbers
except for '2' are odd numbers, and if you add two odd numbers, you get an even number,
which can't be a prime number. And a similar argument probably knocks out subtraction.
So we're going to go out on a big limb here, risk looking foolish, and state that as far
as we're concerned, there's no way in general that a prime number can be "made of"
other prime numbers, and that accordingly, we don't have to worry about coming up
with a name for such a thing.
We'll be watching the watch-list for other contributors to come along and shoot down
our whole shoddy though carefully-constructed line of reasoning.
A number that is not a prime number is called a composite number because it can be made by multiplying prime numbers together. For example, 6 is a composite number that is the product of multiplying the prime numbers 2 and 3 together.
No composite numbers are prime. A composite number is a number that can be made by multiplying other numbers. A prime number is made only by one and itself. Therefore no number can be both prime and composite
a prime number is a number that can not be made by multiplying. 1, 3, 5, 7 are prime numbers.
No because 2 is an even number which is also a prime number
1,890
Any number can be made up from those numbers.
Integers greater than 1, that are not prime numbers, are called composite numbers, because they are "made up of" more than one prime factor.
A composite number is made up of a product of prime numbers. It might be considered a non-prime number.
15 is made of the two prime factors, 3 and 5.
It is 2310.
To distinguish them from prime numbers. Composite means "made up of various parts or elements." Prime numbers have one and only one factor pair. Composite numbers have a various number of factor pairs, but always more than one.
