Question

Which is the smallest pair of co prime

Answer 1

Answer:

1 and 2 is the smallest pair of co prime

perhaps this is right

Answer 2

The smallest pair of co-prime numbers can be found in the following way:

Let us first understand the prime numbers and co-prime numbers.

1. Prime numbers: These are the integers that can be divided only by two numbers.

• The first number is 1.
• The second number is by the same number itself.

2. Co prime numbers: These form a pair of two integers that have only one common factor as its divisor and that number is only 1. Other factors are not common between the two numbers in the pair.

3. Smallest pair:

• 1 is the number that is divisible by 1 itself.
• 2 is the number that is divisible by 1 and 2.
• In these numbers, the common factor is only 1 and is the smallest pair.

Hence, pair of (1,2) is the smallest pair of co-prime numbers and we can say that 2 is co-prime to 1.
