The coolest number (1 Viewer)

[RealiseNothing]

531441 is the coolest number in my opinion (and for a good reason).

My challenge: find out what makes it so cool.

I think the coolest number is:

01189998819991197253

 

[Parvee]

you can square root it and also cube root it.
There probably other things as well

There's many things you can do with the number.

But there's one really cool thing (imo) about it.

 

[maokao]

I can't find what it is

The same thing in common is that you made both numbers up on the spot?

Is it bad that I forgot what a prime factor is and had to look up the definition? (haven't looked at that stuff since year 7 or so )

You're getting close.

Have a look at 531441 (maybe even backwards?)

 

[Absolutezero]

531,441 = (5+31+44+1)^3 = 81^3
531,441 = (5+3+14+4+1)^4 = 27^4

 

[RealiseNothing]

531,441 = (5+31+44+1)^3 = 81^3
531,441 = (5+3+14+4+1)^4 = 27^4

There's more.

But very nice finding that.
