What number should be placed instead of the asterisk in number 702*8 to get a number divisible by 6?

Result

x1 =  1
x2 =  4
x3 =  7

#### Solution:

$702x_{8} | 6 \ \\ 6=2 \cdot \ 3 \ \\ \ \\ 7+0+2+x+8 | 3 \ \\ 7+0+2+x+8 | 3 \ \\ 17+x |3 \ \\ 8+x |3 \ \\ \ \\ x_{1}=1$
$x_{2}=x_{1}+3=1+3=4$
$x_{3}=x_{2}+3=4+3=7$
