Question

what are co prime. number​

Answer 1

Step-by-step explanation:

The sum of any two coprime numbers is always coprime with the product of the same two coprime numbers.

For eg: The sum of 2 and 3 is 5 and the product of 2 and 3 is 6. Hence, 5 and 6 are coprime numbers.

• What are Co-prime number ?

$\bold{ \bf{Answer :-}}$

➣ What are the Co-Prime Numbers?

• A Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be 1.
• Co-prime numbers are also known as relatively prime or mutually prime numbers.
• It is important that there should be two numbers in order to form co-primes.

➣ Properties of Co-Prime Numbers

Some of the properties of co-prime numbers are as follows :-

• 1 is co-prime with every number.
• Any two prime numbers are co-prime to each other.
• Any two successive numbers/ integers are always co-prime.
• The sum of any two co-prime numbers are always co-prime with their product.
• Two even numbers can never form a coprime pair as all the even numbers have a common factor as 2.
• If two numbers have their unit digits as 0 and 5, then they are not coprime to each other.

➣ Example of Co-Prime Numbers

1. 21 and 22
2. 18 and 35
3. 25 and 14
4. 35 and 39

➣ How do you Find the Co-prime of a Number?

➠ To find the co-prime of a number, find the factors of the number first.

➠ Then, choose any number and find the factors of the chosen number.

➠ All the numbers which do not have any common factor other than 1 will be the co-prime of the given number.
