I'd hate to give you a definition like, "Related pairs of numbers are pairs of numbers that are related" so let's just go with an example. Let the first number of a pair represent a quantity of bicycles. Let the second number represent the number of tires per bicycle. With 1 bicycle you would have 2 tires, with 2 you would have 4 and so on.
(1,2)(2,4)(3,6)(4,8) are related pairs of numbers.
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
Yes. Factors are numbers that multiply to create a product.
There is an infinity of pairs of numbers with a GCF of 4. If p and P are two distinct primes, then 4p and 4P are such a pair. There are other ways to construct such pairs, but one infinity should suffice.
Any pair of prime or relatively prime numbers.
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.

Amicable pairs are two numbers that are related in such a way that total of the divisors of each is the same as the other number. This is the case of numbers 220 and 284.
If there are n numbers in the group, there aren2 ordered pairs if the numbers can be repeated,n*(n-1) ordered pairs if the numbers cannot be repeated,n2/2 pairs if the numbers can be repeated,n*(n-1)/2 pairs if the numbers cannot be repeated.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
Assuming the 36 numbers are all different, there are 36*35/2 = 630 pairs.
1,2,3,4,6
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
The factor pairs of 20 are pairs of numbers that can be multiplied together to give 20. The factor pairs of 20 are (1, 20), (2, 10), and (4, 5). These pairs represent all the possible combinations of numbers that can be multiplied to equal 20.
order pairs are 2 numbers that you need to find wich point it goes to
80 has 5 factor pairs.
6.232 6.236
2 + 164 + 146 + 128 + 104 pairs of even numbers can be found whose sum is eighteen.
