In mathematics
[edit]141 is:
- a centered pentagonal number.[1]
- the sum of the sums of the divisors of the first 13 positive integers.[2]
- the second n to give a prime Cullen number (of the form n2n + 1).[3]
- an undulating number in base 10, with the previous being 131, and the next being 151.
- the sixth hendecagonal (11-gonal) number.[4]
- a semiprime: a product of two prime numbers, namely 3 and 47. Since those prime factors are Gaussian primes, this means that 141 is a Blum integer.
- a Hilbert prime
