Indian and western languages

While reading the book Word Power, I was impressed with the etymology analyzing technique. Another surprise was to find Greek and Latin words to have similarity with Samskrit and other Indian languages. Tried putting few of the words here.

Most of the last column are Latin
eka each
onru, onthu one
dvi dual, two
tri tri, three
chatur quad
pancha pentashut
che sexa
sapta septa
asta octa
nava novem
dasha deci

Samskrit and Latin coincide amazingly for 11 to 29 (that is the last number I could find in the page :-)
vimshati viginti

Naama Name
naukaa nau (boat or sea thing)

upari up
adhaka under

jeevan genesis (life)

The 'a' prefix in Samskrit is to mean anti, for eg, avidya (without knowledge). Greek also used 'a' to mean anti, for eg, atom (that which cannot be cut).

The prefix vi in Samskrit has 16 meaning based on the context and the root word it joins with. Two common meaning it derives are negation and intensification. Examples are placed at Beautiful names. The Latin prefix "in" is a close cousin of "vi". The words indecent, injustice for negation and invaluable for intensification are note worthy comparison.

Guess an detail analyze of these two language might throw some more light on the similarity. I tried google to find any such work. Nothing noted in the first page of search.
