When a factor of a number is composed of distinct primes, all the odd primes are raised to a power of 1, while the only even number which is 2 can be raised to any power. For example, the factor of 2134346 is 2*19*56167
Here all the primes are distinct primes.

What is the least odd prime number?

How many distinct prime factors does 168 have?
Three distinct prime factors.
Is a prime number odd?
All prime numbers are odd except one prime number and that is 2.
Is a prime number always an odd number?
Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.
Do perfect squares have an even or odd set of prime factors?
FactorsPerfect squares have an odd number of factors. If you think of factor pairs, the pair of factor that when multiplied together equals the given number, you realize that there are two factors for each pair until you come to the factor that when squared equals the number. For example, the factor pairs of 16 are 1 x 16, 2 x 8, and 4 x 4, giving us the factors of 1, 2, 4, 8, and 16 - an odd number of factors.Prime FactorsHowever, the situation is different with prime factors. It will depend on whether you list every prime factor or only the distinct prime factors. There will always be an even number of prime factors because when you square a number, you double the prime factors, which means you have an even number. That is not the case for distinct prime factors, because when you square a number, you are not adding any additional distinct factors. So, in some cases, there will be an even number of distinct prime factors and sometimes an odd number. Some examples follow.4 = 2 x 2. There are two prime factors, but one distinct prime factor.36 = 2 x 2 x 3 x 3. There are four prime factors and two distinct prime factors.900 = 2 x 2 x 3 x 3 x 5 x 5. There are six prime factors and three distinct prime factors.
All odd numbers less than 30 that are prime?
Prime number are number which have exactly two distinct factors, 1 and itself. Odd primes less than 30 are: 3, 5, 7, 11, 13, 17, 19, 23 and 29.
How many distinct prime factors does 70 have?
The distinct prime factors of 70 are 2, 5, and 7, so it has three distinct prime factors.
Are all odd numers prime?
no, 25 is odd and is not prime 25 = 5 x 5 There is only one even prime number:2, all other prime numbers are odd, but all odd numbers are not prime number
What are the odd prime factors for 56?
The odd prime factor of 56 is: 7
What is the least odd prime number?
3 is the smallest odd prime number.
What is the lowest odd prime number?
The lowest odd prime number is 3 .
Are more prime numbers even or odd?
Odd. The only prime number that is even is two. Since there are many prime numbers that are odd (such as 3, 5, etc.), there are more odd prime numbers than even.
How many distinct prime factors does 168 have?
Three distinct prime factors.
Is a Conjecture is false all prime numbers are odd?
All prime numbers are not odd. 2 is a prime, 2 is not odd.
Is 59 odd and composite?
No, it is odd and prime.
Why are all odd prime?
Not all odd numbers are prime. Prime means you can only divid a number by itself.
