A composite number is any number which has factors apart from 1 and itself.
So most numbers between 20 and 40 are composite:
20=2×2×5
21=3×7
22=2×11
24=2×2×2×3
25=5×5
26=2×13
27=3×3×3
28=2×2×7
30=2×3×5
32=2×2×2×2×2
33=3×11
34=2×17
35=5×7
36=2×2×3×3
38=2×19
39=3×13
40=2×2×2×5
The only ' numbers (having no factors apart from 1 and themselves) between 20 and 40 are: 23, 29, 31, 37.
