There is no prime number from one to a hundred that has more factors than any other prime number. By definition, a prime number has exactly two factors, 1 and itself. The number 1 has only one factor - itself. All prime numbers have exactly the same number of factors - two. Composite numbers have more than two factors.

If a number has 5 factors then it most certainly is not prime. Hence there is some confusion as to what you are asking here.

Kind of. The only prime number that is even is 2.

Prime numbers are numbers that have only 2 factors, 1 and itself. The number one is not prime or composite. Most prime numbers are odd. There is only one composite even number, 2.

Almost all prime numbers are odd. There is only one prime number that is even - the number 2. A prime number is a number with two and only two factors: 1 and itself. All even numbers greater than 2 are divisible by 2, which means they have more than two factors, so they cannot be prime numbers.All prime numbers except 2 are odd.

All prime numbers have exactly two factors. There is not a prime number below 50 that has the most factors since they all have the same number of factors.

Unless you specify a range, there will always be a number with more prime factors. As it is, 63 only has two of them.

Hi... Every integer can be expressed as the product of prime numbers (and these primes are it's factors). Since we can multiply any integer by 2 to create a larger integer which can also be expressed as the product of primes, and this number has more prime factors than the last, we can always get a bigger number with more prime factors. Therefore, there is no definable number with the most primes (much like there is no largest number)!

512 = 29 or 768 = 28*3 have 9 prime factors each.

30

The number 6. Its prime factors are 1,2 & 3 * * * * * Most mathematicians would argue that the correct answer is 2*3*5 = 30 on the grounds that 1 is NOT a prime.
