We can easily verify that none of the entries in the first seven rows of Pascal's triangle are divisible by 7: - - - - - - 1 - - - - - - 1 - - 1 - - - - - 1 - - 2 - - 1 - - - - 1 - - 3 - - 3 - - 1 - - - 1 - - 4 - - 6 - - 4 - - 1 - - 1 - - 5 - -10 - -10 - - 5 - - 1 -1 - - 6 - -15 - -20 - -15 - - 6 - - 1 +

However, if we check the first one hundred rows, we will find that only 2361 of the 5050 entries are not divisible by 7. - -Find the number of entries which are not divisible by 7 in the first one billion (109) rows of Pascal's triangle.
