Exactly! Your understanding is correct.

Explanation:

Coprime Numbers (also known as relatively prime numbers) are pairs of numbers whose highest common factor (HCF), also known as the greatest common divisor (GCD), is 1. This means that the only positive integer that divides both numbers is 1.

For example:

• $8$ and $15$ are coprime because the only common divisor between them is 1. Their HCF is 1.
• $14$ and $25$ are also coprime, as their only common divisor is 1.

Additional Notes:

• Coprime numbers don’t need to be prime themselves. For instance, 8 and 15 are both composite numbers, yet they are coprime.
• Being coprime is a relationship between two numbers. A number by itself is not "coprime"; it must be compared to another number to determine if the pair is coprime.
