In the list of co-prime numbers from 1 to 100, there are many pairs that can be listed as co-prime numbers based on the above properties.
There are multiple such combinations where 1 is the only common factor. Any two consecutive numbers have 1 as their common factor.Ĭonsider a few pairs of such numbers. All pairs of two consecutive numbers are co-prime numbers.For example, 2 and 3, 5 and 7, 11 and 13, and so on. We can check any two prime numbers and get them as co-prime. Two prime numbers are always co-prime.For example, 5 and 9 are co-prime numbers. The sum of two co-prime numbers is always co-prime with their product.Two even numbers cannot be co-prime numbers as they always have 2 as the common factor.1 forms a co-prime number pair with every number.The Least Common Multiple (LCM) of two co-primes is always their product.For example, 5 and 9 are coprime numbers, there, HCF (5, 9) = 1. The Highest Common Factor (HCF) of two coprime numbers is always 1.Co-prime numbers can be identified easily with the help of some properties that are explained below:
