There are thousands of conversion factors and it is not possible to list them all.
There are over 30 units of length listed in Wikipedia "unit of length" - some are more common than others but most are in use. The count does not include the 20 or so SI prefices (milli, centi, kilo etc), making around 50 units in all.
Each pair of measurement units will have two conversion factor: from A to B and from B to A. So just lengths will give rise to approx 50*50 (or 2500) conversion factors. Then there are measures for area, volume, mass, weight, force, work, ...
If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
simplest form
There is neither a greatest common factor nor common factors of a single number, such as 3654, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 1734, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
That's called the greatest common factor, or GCF.
A very common form of sodium chloride is granular, table salt.
You check whether numerator and denominator (top and bottom) of the fraction have common factors. Then you divide both by the common factors. Continue, until there are no more common factors.
It is then in its simplest form
It is already in simplest form because they have no common factors.

If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
Short answer: There is none. There are not common factors of a single number because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, there cannot be a single number that has the greatest number of common factors.
There are not a greatest common factor, a least common factor, or common factors of a single number, such as 57, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are no common factors.
simplest form
There are no common factors between 99 and 130, so it is in its simplest form
ATX, Actually todays most common motherboard form factor used is MicroATX
If it has no prime factors in common. The prime factors of 16 are all twos and the prime factors of 27 are all threes. 16/27 has to be in simplest form.
