Co-Prime Numbers from 1 to 100
By BYJU'S Exam Prep
Updated on: September 25th, 2023
From 1 to 100, the coprime numbers are (2,3), (3,5), (5,7), (11,13), (13,14), (17,19), (21,22), (28,57), (29,31), (41,43), (59,61), (71,73), (87,88), and (99,100). Co-prime numbers are the pair of numbers that share only 1 as their common factor. For a set of co-prime numbers, there must be at least two different numbers. There is only one common factor among such numbers, which is 1.

Co-Prime Numbers Between 1 and 100
According to the definition of a co-prime number, two numbers are considered co-prime if their Greatest Common Factor (GCF) is 1. A and B are co-prime numbers if the only factor they have in common is 1. In this instance, it is said that (a, b) form a co-prime pair. Relatively prime numbers are another name for co-prime numbers.
We first determine the Greatest Common Factor (GCF) of any two numbers in order to determine if they are co-prime. We can say that they are co-prime if their GCF is 1.
- A pair of coprime numbers’ Highest Common Factor (HCF) is always 1.
- A pair of co-primes’ products is always their Least Common Multiple (LCM).
- With each number, 1 creates a pair of co-prime numbers.
- Since two even numbers always have 2 in common, they cannot both be co-prime numbers.
Summary:
Co-Prime Numbers from 1 to 100
(2,3), (3,5), (5,7), (11,13), (13,14), (17,19), (21,22), (28,57), (29,31), (41,43), (59,61), (71,73), (87,88), and (99,100) are the co-prime numbers between 1 and 100. The pair of numbers known as co-prime numbers which have only 1 in common.
