Mathematicians have discovered a surprising pattern in the expression of prime numbers, revealing a previously unknown “bias” to researchers. Primes, as you’ll hopefully remember from fourth ...

Let’s break that down a bit. The square brackets ⌊ and ⌋ indicate that you should round down the value inside them. So, for example, ⌊ 1.7 ⌋ = 1 and ⌊ 1.12111167545 ⌋ = 1.

Prime numbers are only divisible by themselves and one. Robert Brook via Getty Images. In the 17th century, French monk and mathematician Marin Mersenne developed a method to find prime numbers ...

Prime numbers have a remainder of either 1 or 2 when divided by 3 (except for 3 itself), so you might guess that half the primes up to N have a remainder of 1 and half have a remainder of 2. That ...

The largest known prime number has been discovered by an amateur researcher and former Nvidia employee. The new number is 2 136,279,841 – 1, which beats the previous title holder (2 82,589,933 ...
