A trillion.
It has 21 zeros, because 'Giga' means 'a Billion'. Thus, one GigaTrillion is 1 Billion-Trillion. A billion has 9 zeros, and a trillion has 12 zeros. However, if you are referring to the United Kingdom, a billion has 12 zeros and a trillion has 18 zeros, so it would be 30 zeros.
Simply take 4 times 3 without all of the zeros = 12 Now put 12 zeros back (total number of zeros is 13 so take one away) 400,000 (5 zeros) X 300,000,000 (8 zeros) = 12,000,000,000,000 (12 zeros)
12 zeros in a trillion.
1,000,000,000,000 is 1 trillion a 1 followed by 12 zeros a 1 followed by 15 zeros is 1 quardrillion
If you mean a number followed by 12 zeros then it is a trillion: e.g. 1,000,000,000,000
As a number there are 12
