prime number

If you consider 1 and the prime number itself as factors then: 2If you do not consider 1 and the prime number as factors then: 0A prime number is one that does not have any factors apart from 1 and itself.

Each of the 25 prime numbers from 1 to 100 has exactly two factors, 1 and the number itself. The other 75 numbers from 1 to 100 are not prime numbers because none of them have exactly two factors.

2.

No. For example, 30 has the factors 1, 2, 3, 5, 6, 10, 15, 30; while 31 only has the factors 1 and 31 - in other words, it's a prime number. Note that there are arbitrarily large prime numbers (there is no last prime number); each of them has exactly two factors.

If the numbers are prime numbers, the prime factor of each number is the number itself. If the numbers are not prime numbers, the prime factors of each number are each of the prime numbers by which the number in question can be divided without a remainder.

Prime numbers have as factors the number 1 and their own number. Example: 37 is a prime number because its only factors are "1" and "37". If the prime number had further factors, it would no longer be prime.

Prime numbers

You factor the number into prime factors, dividing each prime out.

43 is a prime number because it has exactly two factors, 1 and 43. 33 and 63 each have 3 as a factor as well as 1 and themselves, so they are composite numbers.

Each digit is a prime number that has only two factors which are itself and one The prime factors of the number 22 are 2 and 11

Each prime number has 2 factors: 1 and itself.

3, 11, and 17 are prime numbers each having exactly two factors, 1 and the number itself. 6, 9, and 14 have more than 2 factors and therefore are composites.

210=1024, which has factors of 2i with i between 0 and 10 inclusive.ExplanationIf the prime factorization of a number is p1a*p2b*p3c...the number of factors is (a+1)*(b+1)*(c+1)... [because each pi can be raised to the 0, 1, 2,..., up through the exponent, so there are a+1 choices for the exponent of p1, b+1 choices for the p2, etc.]. But because 11 is prime, there can only be one pi that will yield exactly 11 factors [if, for example, there were two prime factors of the number, you would need (a+1)*(b+1)=11 but because 11 is prime, this won't work unless one of a or b is zero] . 2 is the smallest prime number, and 210=1024 is the smallest whole number with exactly 11 factors.

Distinct prime factors are the prime factors that are distinct (or different) from each other. A list of distinct prime factors is a list of one of each different prime number that is a factor. For example, the prime factors of 8 are 2, 2, and 2. The only distinct prime factor is 2, which occurs multiple times.

Just two: 1 and the number itself.

4096 is the smallest number with exactly 13 factors. (Including 1 and itself as factors).192 is the smallest number with exactly 13 properfactors, (excluding the number itself).120 is the smallest number with at least 13 factors (it has 16 factors)To find the smallest number with exactly N factors (for example, N=12):Factor N into primes, (for example, 12= 2*2*3Subtract 1 from each of the prime factors (for example, 1,1,2)Sort them by largest first (for example, 2,1,1)Raise successive prime numbers to these powers (for example, 2^2,3^1,5^1)Multiply these together (for example: 4*3*5 = 60; 60 is the smallest number with exactly 12 factors).

No - because its factors include each of the two prime numbers.

Take each number in turn, call it "n", and check whether it has any factors f, such that 1 < f < n. If it doesn't, it is a prime number.Take each number in turn, call it "n", and check whether it has any factors f, such that 1 < f < n.

it is easier to find the prime factorization because you do not have to keep multiplying over and over and over again!!!!

Factor each number to its prime factors, look for the prime factors that appear in every single number and eliminate any prime factor tat doesn't appear in each number. Multiply what's left back together and you'll have the GCF.

3, 11, and 17 are prime numbers having exactly two factors, 1 and the number itself. 6, 9, and 14 have more than two factors each, so they are composite numbers.

They only have two factors each.

When each one of them is a prime.

A prime number has no factors other than 1 and itself. Each multiple of fifteen includes 3, 5, and 15 among its factors.
