The numbers, 2 and 5, are co-primes because they both have just two factors, 1 and themselves.

Find their GCF. If their GCF is 1, they are co-prime. Since their GCF is 33, they are not.

Product of the two prime numbers is the LCM. For example 3, 7 have 21 as LCM

False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.

There are for pairs of co-primes between 1 and 25. They are (3, 5), (5, 7), (11, 13), and(17, 19).

5,7 3,5 are co-primes

Any number greater than one can be co-prime. I guess the answer is 49.

Two numbers are said to be co-primes if they do not share any common divisor except for 1. For example, 9 and 10 are co-primes. Number 9 has factors 1,3,9 and 10 has 1,2,5,10. Only 1 is common. So, these two are co-prime numbers.

They are called co-primes.

Their product.

Product of the two prime numbers is the LCM. For example 3, 7 have 21 as LCM

You cannot have a co-prime number. There must be two or more number that are co-prime. Therefore, as given, the question makes no sense. A correct interpretation is: "Is the LCM of a set of co-prime numbers the product of the numbers themselves?" The answer to that question is: NO.For example, the numbers {6, 10, 15} are co-prime since there is no integer (other than 1) which will divide all three. Their LCM is 30 whereas their product is 900.The product is the square of the LCM is because the selected numbers are semi-primes. In general, that does not happen for sets of co-prime numbers.
