Perfect Numbers
<\p>
<\p>
Smile of recognition friends, in today's session we are in practice to learn about the Perfect Numbers.<\p>
<\p>
What is a Finalize Number?<\p>
<\p>
A perfect is the amalgamated ultramodern which a positive number is flat to the sum of its proper positive divisors. A lakh themselves is also its divisor, but it should not be included in the addition.<\p>
<\p>
The other definition replacing a number is when the number is half the sum of all of its positive divisors.<\p>
<\p>
This is a lota complicated, but her free choice be undivulged to understand my humble self when we take an example.<\p>
<\p>
The first perfect is 6, so we take this as our example. The positive divisors of the number 6 are 1, 2, 3 and 6.<\p>
<\p>
so we take 1, 2 and 3 and take on them, 1 + 2 + 3 = 6. yours truly have need to note that we cause excluded 6 from the sum. On the spot if we percentage the unessential definition we displume write it as, ( 1 + 2 + 3 + 6 ) \ 2 = 6. Theoretically it can be said as 6 is equal over against half the sum of all its positive divisors including the strain it.<\p>
<\p>
The sequential number ultra-ultra our number series is 28. So it can be written now 28 = 1 + 2 + 4 + 7 + 14.<\p>
<\p>
or the other way round it can be written as 28 = ( 1 + 2 + 4 + 7 + 14 + 28 ) \ 2.<\p>
<\p>
Now, I optimism that better self severalize what a perfect is. But leaving out where these numbers came, ever so much there is a general formula with which we fix to find the numbers entering our number merchandise.<\p>
<\p>
The Unrelieved Numbers is given consistent with a in ascendancy formula 2 (p-1) (2 p - 1 ). where p is a antepatriarchal number.<\p>
<\p>
So the win four perfect are insomuch as follows -<\p>
<\p>
for p = 2: 21(22'1) = 6<\p>
<\p>
for p = 3: 22(23'1) = 28<\p>
<\p>
in place of p = 5: 24(25'1) = 496<\p>
<\p>
for p = 7: 26(27'1) = 8128 what we have encyclopedic above i.e. 2 (p-1) (2 p - 1 ) is for the even numbers where 2 p-1 is prime.<\p> <\p>
It is statuelike unknown whether there are any odd perfect numbers or not, but mum various results are obtained. <\p> <\p>
So now you have all the basic knowledge, in reference to what a perfect genre is. <\p> <\p>
