Solution:

Choices A, B, and E are all very close to $13579$ , and choice C multiplies $13579$ by a tiny number, making it much smaller.

Choice D divides by $\dfrac{1}{2468}$ , which is the same as multiplying by $2468$ . This makes it thousands of times larger than $13579$ , so it is the largest.

Thus, the correct answer is D .
