Using numeralogy with runes?

[Big Dipper]

So I just got some black toumaline beads, about 122 of them and I got them for the algiz rune. Algiz's number is 15, so If I go to make a rosary for it would I want 100, 111, or a number that is a multiple of 15, like 90?

And when it goes for other runes, when would be good a time to use a rune with a multiple of it's number and not just a specific number like 9, 100, 111 and so on?

As I know, the number 100 is always good

Either one of the options work.

Either one of the options work.

since im doing a nauthiz rune for discipline during saturn's regrade, should I avoid the hour of saturn, or is it not affected?

You can do it on Saturns hour.
