Euclid (born approx. 300 BCE) discovered that the first four perfect numbers are
generated by the formula (2P-1)(2P – 1), where P is prime.
a.) The second part of this formula, (2P – 1), is a special kind of prime number, invented
by a French monk, called a
prime (sec. 2.1).
b.) Show how you would use this formula (2P-1)(2P – 1)with P= 2. You should get the
first perfect number, 6. Caution: in the first part, (2P-1), all of the P-1 is in the
exponent. In the second part, (2P – 1), only the P is in the exponent.
c.) Show how you know 6 is perfect by showing what its proper divisors add up to.
d.) Find the second perfect number using the formula (2P-1)(2P – 1)and the next prime
number for P. (Do not use P = 4, since 4 is not prime). TIP: when you are done, you
might do a web search for perfect numbers to see if you are right.
