Large integers

A googol is the large number 10100 or ten to the power of one hundred. In decimal notation, it is written as the digit 1 followed by one hundred zeros: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. Its systematic name is ten duotrigintillion (short scale) or ten sexdecilliard (long scale). Its prime factorization is 2100 × 5100.

A googolplex is the large number , that is, raised to the power of a googol. If written out in ordinary decimal notation, it would be followed by a googol (10100) ‌a physically impossible number to write explicitly .

An ''' () is a Buddhist name for the number 10140 or alternatively for the number 10^{(a\cdot2^b)} as it is described in the Avatamsaka Sutra. The value of the number is different depending upon the translation. It is 10^{(5\cdot2^{103})} in the translation of Buddhabhadra, 10^{(7\cdot2^{103})} in that of Shikshananda and 10^{(10\cdot2^{104})} in that of Thomas Cleary, who may have made an error in calculation. In these religious traditions, the word has the meaning of 'Incalculable or Countless'.'''
