How do you make 725 to octal?

Answer 1

72510 = 13258

In order to convert a number from one base to another, iteratively divide the number by the new base, recording the remainders in reverse order, until the quotient is zero.

725 / 8 = 90 remainder 5

90 / 8 = 11 remainder 2

11 / 8 = 1 remainder 3

1 / 8 = 0 remainder 1
