Question

which one can be co prime of 4​

Answer 1

Answer:

The only common factor is 1 and hence they are co-prime. Any two successive numbers/ integers are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF.

Answer 2

Answer:

There should be a minimum of two numbers to form a set of coprime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are coprime numbers. Co-prime numbers need not be prime numbers always. Two composite numbers like 4 and 9 also form a pair of co-primes.
