To convert a binary number to an octal number, you need to know how an octal number is represented in binary. It is like this:
0 = 000 4 = 100
1 = 001 5 = 101
2 = 010 6 = 110
3 = 011 7 = 111
As you can see, an octal number consists of 3 'bits' (either a 0 of a 1).
Now, to convert a binary number to an octal number, you first have to group the binary digits into groups of 3 bits (starting from the right). Then, you convert every group of bits into octal numbers. This way you get your binary number into an octal one.
For example:
(1010100111010010)2
We group them into groups of 3 bits, starting from the right.
1 010 100 111 010 010
As you see, we have a single digit left. We must add 0's to make it a group of 3 bits.
001 010 100 111 010 010
Then we convert every group into an octal number, according to the table above.
001 = 1 010 = 2 100 = 4 111 = 7 010 = 2 010 = 2
And in this way, you converted a binary number into an octal one.
(1010100111010010)2 = (124722)8
1111111010 = octal 1772
You must first convert them to a common base. For example, convert all to binary.
Convert each "digit" of the octal into a triplet of binary digits, according to the following rule: Octal Binary 0 000 1 001 2 010 3 011 4 100 5 101 6 110 7 111 So, for example, octal 53 = binary 101 011 [= decimal 43]
The answer depends on what you are converting from: binary, ternary, octal, hexadecimal ...
Convert every octal digit into three binary digit: 0->000 1->001 2->010 3->011 4->100 5->101 6->110 7->111
Octal = 52746757 Binary = 101010111100110111101111
1470 octal = 001 100 111 000 binary
In binary this number is equivalent to 11111000011 while in octal it is 3703
Don't. 889 is not an octal number.
1111111010 = octal 1772
221122: Binary = 1000100001000100100010 Octal = 10410442 Decimal = 2232610

128 is not a valid octal number. Please restate the question.
