To convert the octal number \( 6247 \) to binary, follow these steps:
1. **Convert each octal digit to its 3-bit binary equivalent:**
- **6 in octal**: \( 110 \) in binary
- **2 in octal**: \( 010 \) in binary
- **4 in octal**: \( 100 \) in binary
- **7 in octal**: \( 111 \) in binary
2. **Combine these binary representations:**
- **6**: \( 110 \)
- **2**: \( 010 \)
- **4**: \( 100 \)
- **7**: \( 111 \)
So, \( 6247 \) in octal is \( 110 \, 010 \, 100 \, 111 \) in binary.
Combining these, we get:
\[
6247_{8} = 110010100111_{2}
\]
So, the octal number \( 6247 \) converts to the binary number \( 110010100111 \).
