List of Names of Large Numbers

Table Showing the Names of Large Numbers

What are the names of large numbers? You are most likely familiar with millionbillion or perhaps even trillion? Ever heard though of vigintillion, decillionor quattuordecillion? Here is a table with names of very large numbers in math.

Important Things to Keep in Mind about the Names of Large Numbers

1. Perhaps you have heard before people say “zillion,” “gazillion,” “prillion,” and "Mega-Million" for large numbers. These terms are not actual names for very big numbers. You may have noticed that they are not included in the list above. People use these names vaguely to just refer to numbers that are very big and unknown.  

2. It will take you a long time to count very big numbers.

For example1 year has 31,536,000 seconds.

1 quadrillion = 1,000,000,000,000,000

1,000,000,000,000,000 / 31,536,000 = 31,709,791.9838 years

What does this mean? If it takes you 1 second to say each numberit will take you more 31 million years to count from 1 all the way to 1 quadrillion. This is interesting since 1 quadrillion is still very small compared to the numbers that are towards the bottom of the list above.
