WebNumbers. Numbers are an integral part of our everyday lives, right from the number of hours we sleep at night to the number of rounds we run around the racing track and … Euclid proved that 2 (2 − 1) is an even perfect number whenever 2 − 1 is prime (Elements, Prop. IX.36). For example, the first four perfect numbers are generated by the formula 2 (2 − 1), with p a prime number, as follows: for p = 2: 2 (2 − 1) = 2 × 3 = 6 for p = 3: 2 (2 − 1) = 4 × 7 = 28 for p = 5: 2 (2 − 1) = 16 × 31 = 49…
