MathBabbler learned about refactorable numbers while working on a nBAB for the number 88. The MBNA code was modified to check for refactorable numbers and while testing the code he used the number 36, which is refactorable.

MathBabbler Number Analyst (MBNA) output: ========================================= 36 is a natural, whole, integer 36 is even 36 proper divisors are: 1,2,3,4,6,9,12,18, 36 is refactorable (evenly divisable by # of divisors) 36 is abundant (sum of divisors is 55) 36 is unhappy 36 is a Harshad number 36 is not prime 36 is undulating 36 has the prime factors: 2*2*3*3 36 in octal is 044 36 in hexadecimal is 0x24 36 in binary is 100100 (is evil) 36 nearest square numbers: 36 is square (36 is square) sqrt(36) = 6 ln(36) = 3.58352 log(36) = 1.5563 36 is 6^2 36 reciprocal is .02777777777777777777777777777777 36! is 3.71993e+41 36 is 11.4592 Pi years 36 is 1 score and 16 years
