Definition:Right-Truncatable Prime/Mistake

Source Work

1986: David Wells: Curious and Interesting Numbers:

The Dictionary

$739,391,133$

Mistake

The largest prime number in base $10$ that can be 'tailed' again and again by removing its last digit to produce only primes, ending with $739$, $73$, $7$.

Correction

This should be $73,939,133$.

The number given, $739,391,133$, is in fact $3 \times 13 \times 97 \times 241 \times 811$ and so is not actually prime in the first place.

This has been corrected in Curious and Interesting Numbers, 2nd ed. of $1997$.
