Prime numbers only have two factors, one and the number itself.

A Russian doll prime number is a prime number such that successively removing the right-most digit leaves a prime number.For example, 373 is a prime.Remove the last digit: 37 is a prime.Remove the last digit: 3 is a prime.There aer 83 such numbers in base-10 and the largest of these is 73,939,133.

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.

Using prime factorization, there are 2 three digit numbers with 9 factors: 512 and 768. There are no three digit numbers with 10 or more prime factors. 512=2^9 and 768=3*2^8

If you're asking about distinct prime factors, there are eight numbers tied with three of them. If not, 64 has six twos.

The squares of most 2 digit prime numbers. For example 2809, which is the square of 53, has 3 factors : 1, 53 and 2809 itself.

One way to solve this is to multiply the lowest prime numbers together, starting from 2: 2x3=6. 6x5=30. Multiplying by 7 would yield a 3-digit number, so we are looking for all 2-digit numbers with 3 distinct prime factors. We already have 30. 2x3x7=42. 2x3x11=66. 2x3x13=78. 2x5x7=70. So, to answer the original question, the 2-digit numbers that have the most factors in their prime factorization are, in ascending order, 30, 42, 66, 70, and 78.

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.
