Question

Are the following numbers are co- prime? 1) 7 and 15
2) 24 and 34​

Answer 1

Answer:

1) 7 and 15 are not co - primes

2) 24 and 34 are also not co - primes

Step-by-step explanation:

It is because co - primes are the numbers which are prime and Come up with the GCF or HCF of 1.

For example

7 and 11 are co - primes

As they both are prime numbers and so that there HCF is 1.

You can find out if the number is a co - prime or not by finding out their HCF's and their HCF's should be 1 only or you can also see if the number is prime or not..This is the only meaning of Co - primes..If you wanna ask about twin primes, then that is also too easy.

Two prime numbers having a difference of 2,are said to be twin primes. For example-

3 and 5,5 and 7,etc.
