Dividing 127 by 8, quotient will be 15 and remainder will be 7.
Dividing 15 by 8, quotient will be 1 and remainder will be 7.
Dividing 1 by 8, quotient will be 0 and remainder will be 1.
Now reversing the direction of remainder from bottom to up we can get the number in octal format.
Here, the octal form number of FEDB will be 177333.
