Question

which of the numbers is not coprime of the num 299​

Answer 1

Answer:

Step-by-step explanation:299 itself not a coprime

Answer 2

1 and all integral multiples of 13,23,299 are not coprime with num 299

• In number theory, two integers a and b are said to be coprime if the only positive integer that divides both of them is 1. That is there is no common factor other than 1 between a and b.
• Now to find the factors of 299 we have to factorise first 299. The prime factorisation of 299 yields, $299 = 13*23$.
• Now both 13 and 29 are prime numbers. And both divides 299. Now 1 and 299 trivially divides 299.
• Now any number which is integral multiple of 13 or 23 or 299 will have at least one common factor with 299. So they can't be coprime.
• Hence 1 and all integral multiples of 13,23,299 are not coprime with 299.
