Most Common US Mega Millions Numbers — Full Frequency Analysis & Odds

Across our full draw history, the five most frequently drawn main balls (1–70) have been 10, 17, 31, and a tie between 3 and 42, while 67, 51, 65, 45 and 23 have appeared least often. With 70 numbers and 5 drawn per game, each ball's expected share is about 7.1% of draws.

The Mega Ball itself is drawn from its own 1–24 pool since the April 2025 change (previously 1–25) — our statistics page automatically excludes the 36 historical draws in our database where a Mega Ball of 25 was drawn, so current Mega Ball frequency only reflects numbers that can still actually come up.

For 5 balls from 1–70, the mathematical range runs from 15 up to 340. In practice, the middle 70% of real draws fall between roughly 128 and 220, averaging around 174 — very close to Powerball's equivalent range, since the two games use a similarly sized main pool.

Reducing the Mega Ball pool from 25 to 24 numbers actually improved jackpot odds slightly: the current odds are 1 in C(70,5) × 24 = 290,472,336, down from roughly 1 in 302.6 million under the old format. It's a small improvement, but a real one.

Alongside the odds change, jackpots now reset to a $50 million minimum after a win (up from $20 million), every $5 play automatically includes a random multiplier (2X–10X, applied to non-jackpot prizes), and the old $1 Megaplier add-on was retired since the multiplier is now built into the base price.
