Question

Make 5 pairs of co-prime numbers from 4,7,11,13,23,25,31,36,37,42,43,51

Answer 1

Given: The numbers: 4,7,11,13,23,25,31,36,37,42,43,51

To find: Make 5 pairs of co-prime numbers from given numbers.

Solution:

• Now we have given the numbers

                 4,7,11,13,23,25,31,36,37,42,43,51

• Now coprime numbers are those numbers if the only positive integer (factor) that divides both of them is 1 or such that GCD of these numbers is 1.

• So the pairs are:

                 (4, 51), (4, 43), (7, 43), (11, 13), (13, 23)

Answer:

              So the pairs are (4, 51), (4, 43), (7, 43), (11, 13), (13, 23) .
