Eleven numbers less than 105 are relatively prime to 105. They are 82, 83, 86, 88, 89, 92, 94, 97, 101, 103, and 104.

It could be 97 which is a prime number.

86 is not prime, no even numbers except 2 are prime.

The prime factors of 86 are: 2 43

86 and 154 are not relatively prime because they are both even numbers. Relatively prime numbers have no common factors other than 1, and all even numbers have 2 as a common factor.

Prime Factorization of 86The prime factorization of 86 is:2 X 43Both numbers are prime, so that is the prime factorization of 86.

It is 2 because the prime numbers of 86 are 2 and 43

No.

86 is composite, because it has factors other than 1 and itself. The factors of 86 are 1, 2, 43, and 86. All even numbers greater than 2 are composite.

They are 2 and 43

86

86

43 and 2

86 = 2 x 43

no 86 is not prime

86 - 10 = 76

2 and 43 (they are the only ones)

43 because it is 23 more than 20 and 23 less than 86.

Because it has factors of 1,2,43 and 86. Prime numbers can only have 2 factors: 1 and itself. It is composite because it isn't prime. Hope this helps.

There is only one prime factor common to both numbers and it is 2

No 86 is not a prime number because it has more factors than 1 and itself, for example it has the factors 1, 2, 43, and itself: 86.

47 is prime, the rest are composite.

prime factors of 86: 2, 43 prime factorization of 86: 2 x 43

44 is greater than 86/2 which is 43
