What is the maximum 64 bit integer (number) value?

WebDec 26, 2024 · The maximum (unsigned) 64-bit integer is 18446744073709551615. This is (2^64)-1, which is essentially the square of (2^32)-1, which is "about" 4 billion. In general, you can estimate that every 10 bits represents 3 decimal digits. For 64 bits, that means a good estimate would be 16 (from the 4 leftover bits) followed by 18 zeroes (6*3).
