Co-prime numbers : Two numbers which have only 1 as a common fa
to be co-prime or relatively prime or mutually prime numbers.
For example, 10 and 21 are co-primes, because the divisors of 10 are 1
while the divisiors of 21 are 1, 3, 7, 21 and the only factor common to
and 21 is 1.
Some other co-prime numbers are (3,8); (4, 9); (21, 22); (22, 23);
Verify that any two consecutive natural numbers are co-primes.
Let's learn.
Twin Prime Numbers
If the difference between two co-prime numbers is 2, the numbers are
prime numbers.
For example : (3, 5); (5, 7); (11, 13); (29, 31) etc.
