Answer 1

Answer:

5 and 6 are the co-prime numbers between 13 and 15

Answer 2

Answer:

Step-by-step explanation:

Co-prime numbers are a set of numbers where the common factor among them is 1. It implies that the HCF or the Highest Common Factor should be 1 for those numbers. Co-prime numbers are also referred to as ‘Relatively Prime Numbers’.

Eg: If x and y are the co-prime numbers set, then the only common factor between these two numbers is 1.  

 

Co-prime Numbers from 1 to 100

Co-prime numbers are none other than just two numbers which have 1 as the common factor. Some of these co-prime numbers from 1 to 100 are -  

There are several pairs of co-primes from 1 to 100 which follow the above properties. Some of them are:

(1, 99)

(14, 15)

(28, 57)

(29, 31)

(23, 1)

(59, 97) etc.

Co-prime numbers are set of numbers which do not have any common factor between them other than one. This means that their highest common factor (HCF) is 1.

There should be at least two numbers in order to form co-primes.

Co-prime numbers are also called as relatively prime numbers.
