What is the unit digit in the product of following expression?

$\left[(6374)^{1793} \times(625)^{317} \times(341)^{491}\right]$

0

$\left[(6374)^{1793} \times(625)^{317} \times(341)^{491}\right]$

we can clearly see that we have to multiply 6374 and 625 so if we take unit digits of these two, then the product of unit digits of these two numbers will give a unit digit as 0.

I.e = 5 × 4 = 20

so, the unit digit of whole expression will be 0
