The number of zeros is determined by how many times 12 divides into 15!. To determine this, since 12 = 22*3, we will look at how many times 2 and 3 divide into 15!.
2 divides 2,6,10,14 once, 4,12 twice, and 8 three times, so that 2 divides 15! exactly 11 times. 3 divides 3,6,12,15 once and 9 twice, so that 3 divides 15! exactly 6 times.
From this, we can see that 12 divides into 15! exactly 5 times, since 125=210*35. In other words, the base-12 representation of 15! ends in 5 zeros.

There are 9 zeroes in 1.1 billion. There are 6 zeroes in 1 million and 12 zeroes in 1 trillion.
a million has 6 zeroes, a billion 9, and a trillion 12. one million billion trillion is the sum of those, or 6+9+12 = 27 zeroes
one trillion = 1,000,000,000,000 12 zeroes
It depends. A trillion in English-speaking countries, such as the United States: there are twelve zeroes (1,000,000,000,000) A trillion in other countries: eighteen zeroes (1,000,000,000,000,000,000)
there are 12 zeroes in 1 trillion
