What is the similarity between numbers; 85,17,19,4 and 2

The correct answer for the question that is being presented above is this one: " They are all divisors of 6460."

I guess it asks for the Least Common Multiple (LCM) of these numbers.

85 = 5*17

17=17

19=19

4=2^ (2)

2=2

LCM (85,17,19,4,2) = 5 * 17 * 19 * 2^ (2) = 6460.

Conclusion: They are all divisors of 6460.
