From the following numbers identify different pairs of co-primes. 2, 3

1.	From the following numbers identify different pairs of co-primes. 2, 3,4, 5,6,7, 8, 9 and 10.
Answer» The numbers which have only 1 as the common factor are called co-primes, (or) Numbers having no common factors, other than 1 are called co-primes. 2,3; 2, 5; 2, 7; 2, 9; 3,4; 3, 5; 3, 7; 3, 8; 3,10; 4,5; 4, 7; 4, 9; 5, 6; 5, 7; 5,8; 5, 9; 6, 7; 8, 9 and 9,10. These are the different pairs of co-primes with 2, 3, 4, 5, 6, 7, 8, 9 and 10. 1) Any two primes always forms a pair of co-primes. 2) Any two consecutive numbers always form a pair of co-primes. 3) Any two primes cilways form a pair of co-primes. .

From the following numbers identify different pairs of co-primes. 2, 3,4, 5,6,7, 8, 9 and 10.

Answer»

The numbers which have only 1 as the common factor are called co-primes,

(or)

Numbers having no common factors, other than 1 are called co-primes.

2,3; 2, 5; 2, 7; 2, 9; 3,4; 3, 5; 3, 7; 3, 8; 3,10; 4,5; 4, 7; 4, 9; 5, 6; 5, 7; 5,8; 5, 9; 6, 7; 8, 9 and 9,10.

These are the different pairs of co-primes with 2, 3, 4, 5, 6, 7, 8, 9 and 10.

1) Any two primes always forms a pair of co-primes.

2) Any two consecutive numbers always form a pair of co-primes.

3) Any two primes cilways form a pair of co-primes. .
