can 1 be relatively prime?
154465
Two numbers are relatively prime if they have no prime factors in common. ... Therefore, 1 has no prime factors. Since 1 has no prime factors, it obviously cannot have prime factors in common with any other number. So 1 is relatively prime with any other number, including 2.

If 109 were not a prime number, then it would be divisible by at least one prime number less than or equal to √109 ≈ 10.4 Since 109 cannot be divided evenly by 2, 3, 5, or 7, we know that 109 is a prime number.

Remember, the definition of a prime number says that in order for a positive integer to be prime, it must be divisible by exactly two positive integers; however, 1 is obviously divisible by only one positive integer --- itself; therefore, 1 is NOT a prime number because it does not satisfy the definition of a prime ...

If their greatest common factor is 1, then one of the two numbers must be a prime number. Their least common multiple must be the product of the two numbers. For example: 5 and 7 are prime numbers because their only factors are 1 and themselves.

A number 1 is neither a prime nor a composite number. The prime factorization of a number is the expression of the number as a product of its prime factors.

Therefore, one (1) is NOT an odd prime number because it's not a prime number; it's just an odd number. 1 is not a prime number because it does not meet the definition of prime number: A natural number greater than or equal to 2 that has no divisors other than 1 and itself.

Actually, one can immediately see that 50 cannot be prime, because 5 is one of its divisors: indeed, a number ending with 0 or 5 has necessarily 5 among its divisors. The last digit of 50 is 0, so it is divisible by 5 and is therefore not prime.

A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4.

Is 32 prime or composite? ... If the factors of 32 are only 32 and 1, then we know that 32 is a prime number. Otherwise, 32 is a composite number. To explain better, if 32 is only divisible by 1 and 32, then it is a prime number, and if 32 is divisible by more than 32 and 1, then it is a composite number.

A prime number is a natural number, greater than one, that can only be divided by 1 and itself. The number 26 can be evenly divided by 1, 2, 13 and 26, with no remainder. Since 26 cannot be divided by just 1 and 26, it is not a prime number.

One is neither prime nor composite. To be prime, a number must have two positive divisors: the number itself and one.

So by definition, it's going to have 1 and itself and something else. So it's going to be composite. So 2 is prime. Every other even number other than 2 is composite.

For 7, the answer is: yes, 7 is a prime number because it has only two distinct divisors: 1 and itself (7). As a consequence, 7 is only a multiple of 1 and 7.

Two numbers are said to be coprime, if their HCF is 1. But the two numbers can be (1) both prime like 5 and 7, (2) one prime and another composite like 13 and 18, and (3) both composite like 12 and 35. This will answer your question. Two primes are always coprime, by the latter's above definition.

A prime number is such that it is divisible by only itself and one. ... All the other even numbers are not prime because they are all divisible by two. That leaves only the odd numbers. Of course, not all odd numbers are prime (e.g. nine is divisible by three).

For 29, the answer is: yes, 29 is a prime number because it has only two distinct divisors: 1 and itself (29). As a consequence, 29 is only a multiple of 1 and 29. Find out more: What is a prime number?

Is 37 a prime number? For 37, the answer is: yes, 37 is a prime number because it has only two distinct divisors: 1 and itself (37). As a consequence, 37 is only a multiple of 1 and 37.
