Only two: (4, 9) and (6, 6). In all other factor pairs, one of the numbers is not composite.
1, 2, 3, 4, 9, 12, 18, 36 Eight numbers
4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,45,46,48,49,50,51,52 altogether: 36
The composite numbers between 35 and 45 are 36, 38, 39, 40, 42, and 44. In total, there are six composite numbers in that range. A composite number has more than two positive divisors, which these numbers do.
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.
Assuming the 36 numbers are all different, there are 36*35/2 = 630 pairs.
33 and 34 35 and 36 38 and 39
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.
1, 2, 3, 4, 9, 12, 18, 36 Eight numbers
There are 3 composite numbers between 35 and 40. They are 36, 38, and 39.
4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,45,46,48,49,50,51,52 altogether: 36
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.
There are 3 pairs of prime numbers with sum of 36. These are: (31, 5), (29, 7), (23, 13), & (19, 17) Hope this helps! :D
