Persistence of a number - Wikipedia
Usually, this involves additive or multiplicative persistence of a non-negative integer, which is how often one has to replace the number by the sum or product ...
Multiplicative Persistence -- from Wolfram MathWorld
Multiply all the digits of a number n by each other, repeating with the product until a single digit is obtained. The number of steps required is known as ...
Multiplicative Persistence - Highest persistence found? - MathOverflow
The comments in OEIS claim various lower bounds on the size of a number of persistence 12: a comment in 2019 claims 1020585, and a comment in ...
Multiplicative persistence base 10: some new null results
The number of steps, p, that it takes for n to be changed to the single digit end-point, is called the multiplicative persistence of n (Sloane, 1973). The ...

Persistence of a number
In mathematics, the persistence of a number is the number of times one must apply a given operation to an integer before reaching a fixed point at which the operation no longer alters the number.
