Only two: (4, 9) and (6, 6). In all other factor pairs, one of the numbers is not composite.
36 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
12 and 36 are both even numbers greater than 2. They are composite numbers.
They are both composite because they are even. They are composite numbers because 36 can be formed by 6x6 and 72 can be formed by 6x6x2. Since prime numbers means that they are only divisible by 1 and itself, the numbers are not prime numbers. Also, any number greater than 1 is either a composite or prime number, so they are composite numbers.
The composite numbers in that list are 22 and 36 - you know they are composite, because they are even numbers. The other numbers are odd and prime.
There are 3 composite numbers between 35 and 40. They are 36, 38, and 39.
The composite factors of 36 are 4, 6, 9, 12, 18, 36
36 is a composite number because it has more than two factors whereas prime numbers have only two factors.
