560 means fifty six ohms. 561 would be five hundred and sixty ohms. 564 would be five hundred and sixty Kilohms, or, more concisely, point five six Meg.
These are also seen as arrays, pictured here are 33 ohm arrays I soldered together because I did not find any use for them.
When kept loose in a box, they tend to obey Murphy's law and all of them will be hiding white side up. And the one you want will be the one you turn up last.
Because when you find the one you want you stop looking.
