Solve the following congruences. Make sure that the number you enter is $\geq 0$ and $\leq N-1$, where $N$ is the modulus of the congruence. If there is more than one solution, enter the answer as a list separated by commas.

$X_1 - 196 \equiv 567$ $\pmod{51}$
$X_1 =$

$X_2 + 784 \equiv 953$ $\pmod{72}$
$X_2 =$

$(X_3)^2 \equiv 3$ $\pmod{13}$
$X_3 =$

$(X_4)^2 \equiv 1$ $\pmod{8}$
$X_4 =$
