From The TV IV

The numbers or cursed numbers are a set of numbers that recur multiple times in Lost. These mysterious numbers have grown to become a prominent, recurring plot line on the show and is one of the more supernatural aspects of the series. The numbers are first mentioned in "Numbers", although they do appear on many occasions before that episode.

Due to the numbers being one of the biggest recurring mysteries on Lost, criticism was pointed toward Damon Lindelof, who revealed in a TVGuide interview that the true nature of the numbers will never be revealed. This is one of the more persistent criticisms of the series. J.J. Abrams has used a similar non-disclosure technique with another recurring number, 47, which appears in nearly every episode of Alias.

The Valenzetti Equation

In 1962, the Cuban Missile Crisis resulted in the world coming to the brink of nuclear war. With their respective nations having just faced the very precipice of mutual assured destruction, the United States and Soviet Union — under the auspices of the United Nations Security Council — secretly sought Enzo Valenzetti out as a disinterested third party and charged him with the creation of an infalliable mathematical algorithm for the prediction of Armageddon.

Valenzetti's result was the Valenzetti Equation, an equation that predicts the exact number of years and months until humanity extinguishes itself, whether through nuclear fire, chemical and biological warfare, conventional warfare, pandemic disease or over-population. Valenzetti gave numerical values to the core environmental and human factors in his equation: 4, 8, 15, 16, 23 and 42. It is felt by some, such as Alvar Hanso, that only by manipulating the environment and finding scientific solutions will these core factors be changed and thereby give humanity a chance to survive.

The United Nations Security Council buried Valenzetti's findings, but the Valenzetti Equation was the catalyst for the creation of the DHARMA Initiative.

The Numbers

In 1988, slightly more than 16 years before the crash of Oceanic Flight 815, Danielle Rousseau's science team picked up a mysterious short-wave transmission from the island. The transmission was merely six numbers repeated over and over again: 4, 8, 15, 16, 23, 42. She wasn't the only one who heard them. The same transmission was also picked up by a U.S. Navy long wave transmission monitoring station where Leonard Simms and Sam Toomey worked.

Sam Toomey used the numbers to win a $50,000 (Australian) prize for guessing the exact number of beans in a jar — no one had come even close to the correct number in the 40 years the contest was running. After that, bad things started to happen to those around Sam Toomey. He moved to the middle of nowhere to try and limit the damage, but eventually he killed himself with a shotgun to make the bad things stop.

Leonard Simms wound up at the Santa Rosa Mental Health Institute, where he met Hugo "Hurley" Reyes. Leonard kept repeating the numbers over and over, and they eventually became ingrained in Hurley's mind. Hurley played the numbers in a lottery which hadn't had a winner for 16 weeks. He won 114 million dollars. After that, bad things seemed to happen to those around him too, but in a way that made him profit.

Hurley became convinced that the numbers were cursed, so he went to see Leonard, and eventually he found Sam Toomey's house in Australia and learned about the transmission but nothing more. He headed back home to Los Angeles on Oceanic flight 815, which departed from gate 23 on what was planned to be a 16-hour long flight departing at 2:15 P.M. and landing in Los Angeles at 10:42 P.M.

One interesting thing of note is that, when the numbers all appear together, they always appear in order.
