WebFor a repdigit to be prime, it must be a repunit (i.e. the repeating digit is 1) and have a prime number of digits in its base (except trivial single-digit numbers), since, for example, the repdigit 77777 is divisible by 7, in any base > 7. In particular, as Brazilian repunits do not allow the number of digits to be exactly two, Brazilian primes must have an odd … WebAnswer (1 of 2): Before we start, a quick comment on the statement: by “sum of distinct primes” we clearly mean “sum of 1 or more distinct primes”, meaning a prime number is simply represented as itself, even though there’s no “sum” involved.
