7777 - MMMMMMMDCCLXXVII
A four-digit octal number can represent values from 0000 to 7777 in octal notation. In decimal, this corresponds to a range of 0 to 4095, as each digit can take values from 0 to 7, and the total value is calculated as (8^3 \times d_3 + 8^2 \times d_2 + 8^1 \times d_1 + 8^0 \times d_0), where (d_3, d_2, d_1, d_0) are the digits. Therefore, the range of values representable by a four-digit octal number is from 0 to 4095.
7 x 7777 = 54439
