One example could be 4 and 9. Others include 8 and 9, 8 and 15, and 4 and 21.
Yes as for example 34 and 45
Any numbers that don't have common prime factors will do; for example, 23 and 32; 2x3 and 5x7, 3x5 and 2x7, etc.Any two consecutive numbers will have no common factor, for example, 8 and 9 (the first example I gave above), or 100 and 101. However, in the second example, 101 is not a composite number.
