Answer 2

The two numbers don't have any common factor other than 1, the two numbers 10 and 21 are co-primes.

Step-by-step explanation:

In the number system theory, numbers are categorised based on their properties. Today, we are going to learn about one such categorization called coprime numbers. But before we delve deep into it, let us first understand the concept of prime numbers. Prime numbers refer to:

• Natural numbers greater than 1
• Which have only two divisors, those being 1 and the number itself
• In other words, those numbers that cannot be written as the product of two smaller natural numbers
• Example: 2, 3, 5, 7, 11, 13 and so on
