Why 2 is smallest co prime number?

Answer 1

The number 2 is considered the smallest co-Prime number because it is the smallest prime number and has only two distinct positive divisors: 1 and itself. Co-prime numbers are defined as pairs of numbers that have no common positive divisors other than 1. Since 2 can only be paired with odd numbers (like 3, 5, 7, etc.) to satisfy the co-prime condition, it is the smallest number that can be co-prime with another integer.
