This number is a prime.

Argam names are only available for 647-smooth numbers (i.e., no prime factors exceed 647), unless you wish to use any of the extended variants. Argam (AHR-gam, also spelt as arqam, singular form: ragam/raqam) is a numeral set invented and developed by entrepreneur and coder Michael De Vlieger to express numbers written in large number bases.
