Is a number defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits in base-ten, and repeat the process until the number either equals 1 (where it will stay), or it loops endlessly in a cycle that does not include 1. Those numbers for which this process ends in 1 are happy numbers
So
1717 = 2948089
2²+9²+4²+8²+0²+8²+9² = 310
3²+1²+0² = 10
1²+0² = 1
1²+7²+1²+7² = 100
1²+0²+0² = 1
Lol sorry i love maths, and can not avoid doing the calculation
:D
ty @dromzz
1717= 1²+7²+1²+7²
1²+7²+1²+7²=1+49+1+49
1+49+1+49 = 100
100 = 1² => Happy number
Where did you get that 2948089 from? Did I miss something :D
And I also like maths but for some reason, I am typing this comment instead of doing my math homework.
Upss is correct I knew that 1717 is a friendly number, but I did the memory calculation
XD
and then it was that I looked for the reference
Thank you ;)
These things happen :)
I have no idea if that is correct or not, it just looked interesting. (I flunked my maths...)
Lol,
I thought when you said funny numbers you were referring to happy numbers and 1717 is a Happy Followers Number
XD
Btw Congrats,I got excited with the calculation and I forgot to congratulate you :D
