Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 343, 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.

Examples: The common factors of 14 and 343 are 1 and 7; the greatest common factor is 7.

The common factors of 98 and 343 are 1, 7, and 49; the greatest common factor is 49.

The common factors of 100 and 343 are only 1; the greatest common factor is 1.
343 and what other number? 343 = 7 x 7 x 7
