341 (three hundred [and] forty-one) is the natural number following 340 and preceding 342.

In mathematics

341 is an octagonal number, a centered cube number and a super-Poulet number. It is the sum of seven consecutive primes (37 + 41 + 43 + 47 + 53 + 59 + 61). 341 is a palindrome and repdigit in bases 2 (1010101012), 4 (111114), 8 (5258), 17 (13117) and 30 (BB30).

341 is the smallest Fermat pseudoprime; it is the least composite odd modulus m greater than the base b, that satisfies the Fermat property "bm−1 − 1 is divisible by m", for bases up to 128 of b = 2, 15, 60, 63, 78, and 108.
