How do you say 26 digit number? - Answers

Such numbers are best written - and pronounced - in scientific notation. Normally you don't need all the digits, so you can round such a number to an appropriate number of significant digits - for example, 25670000..... Then you express it in scientific notation, in this example, 2.567 x 1025. Edit: I agree entirely with the previous answer but, if you must: The 2-digit name for digits 1-2 followed by "septillion", the 3-digit name for digits 3-5 followed by "sextillion", the 3-digit name for digits 6-8 followed by "quintillion", the 3-digit name for digits 9-11 followed by "quadrillion", the 3-digit name for digits 12-14 followed by "trillion", the 3-digit name for digits 15-17 followed by "billion", the 3-digit name for digits 18-20 followed by "million", the 3-digit name for digits 21-23 followed by "thousand", and the 3-digit name for digits 24-26.
