How do you express a number as the product of powers of its prime factors?
You factor the number into prime factors, dividing each prime out.
Which is a prime number 33 43 63?
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.
Factors of each number that is prime?
Just two: 1 and the number itself.
What is the least positive integer that has exactly 13 factors?
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).
What are distinct prime 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.
When you have a number that has exactly two equal factors each factor is called what?
prime number
Each prime no has exactly how many factors?
2.
What numbers have exactly 2 factors each?
Prime numbers
Why are there 25 prime numbers from 1-100?
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.
How do you express a number as the product of powers of its prime factors?
You factor the number into prime factors, dividing each prime out.
How many factors to each prime number have?
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.
Will a greater number always have more factors than a smaller number?
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.
What are facts about each digit of 22?
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
Do prime numbers have more than 1 factors?
Each prime number has 2 factors: 1 and itself.
Which is a prime number 33 43 63?
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.
Factors of each number that is prime?
Just two: 1 and the number itself.
What are all the prime factors up to 100?
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.
