It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
Identify two numbers whose Greatest Common Factor is 24 and Least Common Multiple is 48?The two numbers are 12 and 24.
There can be no greatest common denominator. If you have a set a numbers whose least common denominator is L then 2*L, 3*L, … are all common denominators. There is no end to that sequence and so no greatest.
How about: 18 and 5 or 10 and 9
Numbers for which the sum of the digits is divisible by 9. This is also true for 3. There are other divisibility/multiple tests for other numbers (e.g., numbers that are divisible by 5 end in 5 or 0; numbers whose last two digits are divisible by 4 are divisible by 4)
