who sent the largest amount of men to venezuela to help with the earthquake

The United States appears to have sent the largest number of personnel to help with the Venezuela earthquake response, with a Virginia team of 80 people and a California team of 70 people reported, for a total of 150 responders.

Other major contributors

• Mexico sent 250 military rescue personnel plus dogs, aircraft, and medical supplies.

• France said it was sending 85 search and rescue specialists.

• Colombia said it would send more than 60 rescuers and humanitarian aid.

• Türkiye dispatched a 67-member team of search-and-rescue experts, medics, and aid workers.

Important nuance

If you mean strictly “men” in the sense of male personnel, the reporting I found does not break the teams down by gender, so the safest answer is that the U.S. sent the most personnel overall among the sources reviewed.

TL;DR

The country that sent the largest rescue force to Venezuela, based on the reporting I found, was the United States.
