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.
3 and 13
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.
