Answer for any no1 cube 5 cube 3cube answer is 153?

Answer 1

According to G H Hardy (in "A Mathematician's Apology"),

There are just four numbers, after unity, which are the sums of the cubes of their digits. These are:

13 + 53 + 33 = 153

33 + 73 + 03 = 370

33 + 73 + 13 = 371

43 + 03 + 73 = 407.

He added that "these are odd facts, very suitable for puzzle columns and likely to amuse amateurs, but there is nothing in them which appeals to the mathematician."
