(461 + 462 + 463 + 464) = 461 x (1 + 4 + 42 + 43) = 461 x 85. = 460 x (4 x 85). = (460 x 340), which is divisible by 10.
Avhinash Yadav
461+462+463+464=4(61+62+63+64)=4(250) because of divisibility rule this no is divisible by 10 .so the answer is 10
Amaljith
4^odd= end with 4
4^even= end with 6
So 4^61+4^62+4^63+4^64= xxxxx4+xxxxx6+xxxx4+xxxxx6
=xxxxxxxx0
End with zero
So divisible by 10
