7A216
Let's first convert hexadecimal value of 7A2 into binary
Hexadecimal     Binary
    0           0000
    1           0001
    2           0010
    3           0011
    4           0100
    5           0101
    6           0110
    7           0111
    8           1000
    9           1001
    A           1010
    B           1011
    C           1100
    D           1101
    E           1110
    F           1111
Use this table to convert from hexadecimal to binary
Converting 7A2 to binary
7 => 0111
A => 1010
2 => 0010
So, in binary 7A2 is 011110100010
Now, let's convert that binary number into octal
Octal   Binary
    0           000
    1           001
    2           010
    3           011
    4           100
    5           101
    6           110
    7           111
Use this table to convert from binary to Octal
Converting 011110100010 to Octal
011 => 3
110 => 6
100 => 4
010 => 2
So, in Octal 011110100010 is 3642
Answer: 3642
