Question

Write three pairs of co-prime numbers.​

Answer 1

Answer:

Now, coming towards our main question, what is the definition of coprime numbers?

‘Co’ refers to a ‘pair’. So, we can define a pair of integers, let's say a and b, as coprime or primes to each other or mutually prime or relatively prime if:

the only positive integer that divides both of them to give a remainder zero is 1

In other words, the HCF of the two numbers is 1

Coprime numbers are denoted as gcd(a, b)=1 or (a, b)=1 or as “a is prime to b”

Answer 2

Answer:

(2,3), (3,5),(5,7)

Step-by-step explanation:

Some of the pairs of coprime numbers from 1 to 100 are (2,3), (3,5), (5,7), (11,13), (17,19), (21,22), (29,31), (41,43), (59,61), (71,73), (87,88), (99,100) So this was the basic difference between the prime and the coprime numbers.
