Factors of 32: 1, 2, 4, 8, 16, and 32.
Factors of 34: 1, 2, 17, and 34.
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, and 36.
Factors of 38: 1, 2, 19, and 38.
It looks like they all have.
14 and 28 are two even numbers between 10 and 30 whose greatest common factor is 14.
All even numbers are composite, because 2 is a factor of every even number.
No. 24 has 3 as a factor. 30 has 15 as a factor.
If you are including 10 and 30 there are 11 even numbers. If you are not counting 10 and 30 there are 9 even numbers between 10 and 30.
the only factor (divisor) between 30 and 64 are 2, this is also a factor of 42 & 196 working upwards: 1 is always a factor of integers 2 is a factor of all even numbers 3 is a factor of 30 & 42, but not 64 or 196 4 is a factor of 64 & 196, but not 30 or 42 5 is a factor of 30, but not the others 6 is a factor of 30 & 42, but not 64 or 196 7 is a factor of 42, but not the others 8 is a factor of 64, but not the others 9 is not a factor of any of the numbers 10 is a factor of 30, but not the others I could continue, but it gets worse from there, with only occasional numbers being factors...
40, 50 and 60
Even numbers are integers that are divisible by 2. Between 1 and 30, the even numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30. These numbers can be obtained by starting from 2 and adding 2 successively until reaching 30.
The even numbers between 26 and 36 are 28, 30, 32, and 34.
There aren't any. 2 is the only even prime number, so no other even numbers can be prime. There can be no even numbers between 30 and 50 that are prime.
