Which prefix indicates a factor of 10^16?

The prefix that indicates a factor of 10^16 is Peta. In the International System of Units (SI), prefixes are used to denote scalar multiples of units. Each prefix corresponds to a specific power of ten, and understanding these can help in interpreting measurements accurately.

Peta is defined as 10^15, and while it may seem close to the required value of 10^16, understanding SI prefixes clarifies that peta corresponds to a factor of 15, not 16. The prefix that corresponds to 10^16 is actually Exa.

Exa signifies a magnitude of 10 raised to the power of 18. The subsequent prefixes, Zetta (10^21) and Yotta (10^24), represent even larger magnitudes. It's important to familiarize oneself with these prefixes as they are commonly used in fields involving large numbers, such as in computing and data storage capacities.
