88 is a composite number because it is an even number. All numbers greater than 8 and less than 100 are composites if they are even numbers, if they are multiples of 3 or 7, or if they end in 5 or 0.
2, 4, 6 All even numbers have even multiples.
The numbers 3,6 and 9 are all multiples of 3 because 3 can go into all of them evenly.
To any set that contains it! It belongs to {14}, or {14, sqrt(2), pi, -3/7}, or all whole numbers between 3 and 53, or multiples of 7, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, etc.
Yes, all multiples of 3 are composite except for 3 itself which is a prime number.
no take 3 for example. 3 6 9 3 x 3= 9 so that's composite.
27 and 18 are both composite numbers. They are multiples of 3.
All multiples of 9 are composite numbers; however, 9 itself is not a prime number. Its factors are 1, 3, and 9.
No, prime numbers have only two factors: 1 and itself. Composite numbers have at least 3 factors.
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.

Multiples of any number greater than one are composite.
This question is true
But if a number is divisible only by itself and by 1, then it is prime. So, because all the other even numbers are divisible by themselves, by 1, and by 2, they are all composite (just as all the positive multiples of 3, except 3, itself, are composite).
no
Sieves of Eratosthenes is a good way to understand why: For example: Write down all numbers from 1 to 100 2 is prime, so all its multiple are composite, all even numbers except 2 are composite, so erase them. Half of the numbers are already erased 3 is prime, so all its multiple are composite, so erase them. A bit less than one third of the remaining number are erased (multiples of 6 have already been erased) 5 is prime, so all its multiple are composite, so erase them.... and so on with 7 and 11.... Each time a prime number is found all its multiples are to be erased from the list. Thus there are more composite numbers (erased ones) than primes.
