Co prime numbers are two numbers which have only one factor in common, the number one. If the two numbers share any other factor then they are not co prime.
In this case, (1,20) are co prime because their highest common factor is one, which means it is also their only factor.
Coprime numbers are 2 or more numbers that only have the factor of 1 in common. these numbers would be coprime, because the only common factor is 1. If the 2 numbers have more factors in common than 1 they are not coprime.

gcd(1,20) = 1
so 1 and 20 are coprime.
