Question for Maths lovers - Interesting Number Pattern ----> 15

Can you list down multiple characteristics of the number 153? (without Googling please :))

It could be sum of squares, cubes, etc, etc - Can you list down all of them?

  2. Raj, you are right... It is an Armstrong number and so sum of cubes of its digits

    There is more to this :) Good start

  3. 2^2+3^3+4^2+5^2+9^2 = 153, not sure whether squares and cubes can combine

  4. 12^2+3^2=153,
    11^2 + 3^3 + 2^2 + 1^1=153
    6^2+6^2+9^2=153
    2^2+3^2+4^2+4^2+9^2+3^3=153
    2^3+3^3+4^3+2^2+3^2+4^2+5^2=153

    I think there will be more to this..

  5. Few more

    153 = 13 ^ 2 - 4 ^ 2
    153 = 9 ^ 2 + 6 ^ 2 + 6 ^ 2 (as Mahesh said) and also 15 ^ 2 - 6 ^ 2 - 6 ^ 2!
    153 = 2 ^ 7 + 5 ^ 2
    153 = 11 ^ 2 + 2 ^ 5

    There are few more :)
