Prime Factorization Of 40

Faculty's first factoring?

Let me try 40! Say the most common case first. Obviously, the first factor of 40! With only less than 40 numbers, the question arises as to what power each has. Basic numbers are less than 40:

2,3,5,7,11,13,17,19,23,29,31.37.

There are many factors, say 2 out of 40! ? The number of the first number is less than or equal to 40 which has a factor of 2:

r (40/2) = 20.

(R (x) here means to rotate the largest number less than x). Of course, some of them have more than 2 elements. How many of these are at least 2 of factor 2? All people do is:

r (20/2) = 10.

How many of these are 3 out of 2 factors?

r (10/2) = 5.

4 out of 4 factors?

r (5/2) = 2.

5 out of 5 factors?

r (2/2) = 1.

Therefore, the combination of 2 factors is:

20 + 10 + 5 + 2 + 1 = 38.

Similarly, you will get a combination of 3 factors as 3

r (40/3) + r (13/3) + r (4/3) = 13 + 4 + 1 = 18.

Do the rest:

r (40/5) + r (8/5) = 8 + 1 = 9,

r (40/7) = 5,

r (40/11) = 3,

r (40/13) = 3,

r (40/17) = 2,

r (40/19) = 2,

And the rest is 1. So this is the basic factor

40! = 2 38 3 18 5 9 7 5 11 3 13 3 17 2 19 2 23 29 31 31 37.

You can write the calculations of Primen Exporter P in its most compact form.

Plural_ {i = 1} <r (log_p (40)} r (40 / p <i).

This is the sum of 1 in the log base p of 40. A similar formula will allow you to write a formula for the basic element of n! For the public I don't know if there is an easy way ...

Prime Factorization Of 40

The first factoring of the faculty? 3
Will you explore key faculty factors?
For example, what is the basic factorization of 40?
update
The basic factorization of 40 is ... I am looking for the basic factorization of 40! (Factorial 40), which is 40 x 39 x 38 x 37 ... x 3 x 2 x 1
Let me try 40! Say it first, then say the most common thing. Obviously the first factorization of 40! Only less than 40 prime numbers, the question arises, what is the strength of each? There are less than 40 prime numbers:
2,3,5,7,11,13,17,19,23,29,31.37.
There are so many factors, 2 out of 40 say! ? First, the number of numbers less than or equal to 40 whose factor is 2:
r (40/2) = 20.
(Here r (x) means to round the largest number less than x). Of course, some of these are more than a factor of 2. What everyone does is:
r (20/2) = 10.
How many of these are 3 out of 2 factors?
r (10/2) = 5.
4 out of 2 factors?
r (5/2) = 2.
5 out of 2 factors?
r (2/2) = 1.
Therefore, there is a combination of 2 factors:
20 + 10 + 5 + 2 + 1 = 38.
You can also find a combination of 3 factors.
r (40/3) + r (13/3) + r (4/3) = 13 + 4 + 1 = 18.
Rest:
r (40/5) + r (8/5) = 8 + 1 = 9,
r (40/7) = 5,
r (40/11) = 3,
r (40/13) = 3,
r (40/17) = 2,
r (40/19) = 2,
And the rest is 1. So this is the basic factorization.
40! = 2 38 3 18 5 9 7 5 11 3 13 3 17 2 19 2 23 29 31 37.
You can write the strength of the p line in its shortest form.
sum_ {i = 1} <r (log_p (40)} r (40 / p <i).
This is a combination of 40 log base p to 1. A similar formula will allow you to write a formula for the basic factorization of n! For the public n. I don't know if there is an easy way ...
