Not.
No, 39 isn't prime.
No, 13 and 39 are not relatively prime. 13 is a factor of 39.
Here is a factor tree of 39: 39 3 x 13 Since these are prime numbers, the factor tree is finished. The prime factors of 39 are 3 and 13.
The lowest prime number that will divide evenly into 39 is 3, so 3 is a prime factor of 39. 39/3 = 13, and 13 is a prime number that is also a factor of 39. The prime factorization of 39 is 3 x 13.
prime number : 6.5 factor: 13, 3,
39 and 45 are not relatively prime because they have 3 as a common factor. Relatively prime numbers have no common factor greater than 1.
3 x 13 = 39
13
No, 39 is not a factor of 43. Since 43 is a prime number, its only factors are 1 and 43.
No. hcf(39, 182) = 13. Their highest common factor would be 1 if they were relatively prime.
Two numbers are considered relatively prime if they share no common factors other than 1. In this case, 26 and 39 are not relatively prime because they have a common factor of 13 (13 is a factor of both 26 and 39). Therefore, 26 and 39 are not relatively prime.
