Incorrect combined `multipleOf` value when using decimal constraints

[srivastava-diya]

Description

When combining decimal multipleOf constraints (e.g. inside allOf), the resulting combined value can be wildly incorrect instead of the expected mathematical LCM.

Minimal reproducible example

{
   allOf: [
       { multipleOf: 0.2 },
       { multipleOf: 0.3 }
   ]
}

Instance

instance = 0.7

Expected output

Expected a number that is a multiple of 0.6

Actual Output

Thanks for finding this! @Sam-61s, can you have another look at this one?
