Definitions [7]
Co-prime numbers:
Two numbers with only 1 as a common factor are said to be co-prime, relatively prime, or mutually prime numbers.
For example, 10 and 21 are co-primes.
If the difference between two coprime numbers is 2, the numbers are said to be twin prime numbers. For example: (3, 5)
A prime number is a natural number greater than 1 that has exactly two factors: 1 and the number itself.
2, 3, 5, 7, 11, and so on are examples of prime numbers.
Numbers having more than two factors are called composite numbers. 4, 6, 8, 9, 10, and so on are examples of composite numbers.
Prime factors of a number are the prime numbers that divide it exactly.
The HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers.
The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
