The GCF of consecutive odd numbers is 1.
20 and 21
The HCF of the given two numbers is 14
The product of two odd numbers is always odd.
It will be 1
The GCF of consecutive odd numbers is 1.
Two consecutive numbers (pressumably integers) will always add up to an odd number, so this has no solution. If you mean "two consecutive even numbers" or "two consecutive odd numbers", you should quickly be able to find a solution by trial-and-error.
20 and 21
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.

The HCF is the largest number that both numbers can be divided by. If the HCF is 1, that would suggest that the two numbers share no prime factors. Thus, any two numbers which are coprime will have an HCF of 1. Consecutive numbers are good examples here - 15 and 16, 27 and 28, 104 and 105, all have an HCF of 1.
You need at least two numbers to find an HCF.
You need at least two numbers to find an HCF.
