@willettekunesh92578: 6174 Kaprekar's Constant. Please note this doesn't work for all repeating numbers like 1111 2222 and so on. One more thing in the python code you see 1 and that means 1000, like 1000-1 and then this process. This was discovered by D. R. Kaprekar in the 1900s. #CapCut #kaprekarsconstant #kaprekar #math #maths #EduTok #learnwithme #Science #sciencetok #numbertheorie #numberphile
