First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.

coprime numbers with 18 are : 17 and 19.

Since 25 and 27 are coprime, any third number - even if it shares a factor with one of these numbers - is bound to form a triplet whose HCF is 1.

When a number has no common factors with another, they are called coprime, and an infinite number of such pairs exist. They include any pair involving a prime number, but also such pairs as 12 and 25. It is a simple matter of the two numbers not having any common factors; there is no complicated technical description or proof required.

every number has a limited amount of factors those you could chose any number and find another with that number of factors

Any prime number has two factors: 1 and the number itself.

The prime factors of a squared number are the prime factors, if any, of its square root.

Technically, you can't. You can find the prime factors of a number. If you compare those prime factors to the prime factors of another number, you will see if they have any prime factors in common.

No, since it has at least two more factors other than one and itself, it's by definition not prime. Any such number would always be composite.

Co-prime numbers have a GCF of 1, that is, they don't share any common prime factors. If your number is 15, with a prime factorization of 3 x 5, pick a number that doesn't include 3 or 5. 2 x 11 is 22 15 and 22 are co-prime.

Yes. 1 is coprime to every integer greater than it.

To find the factors of a number you should first break that number down into its prime factors. In this case 65 can be broken down as: 65 = 5x13 To find any other factors, you then multiply any combination of these prime factors together. In this case, the factors of 65 come out as: 1, 5, 13 and 65.
