1142857143

1142857143 is a notable number in the field of mathematics, specifically in the context of cyclic numbers. A cyclic number is a number that, when multiplied by a sequence of natural numbers, generates a sequence of numbers that contain the same digits, although in different orders. The number 1142857143 is a cyclic number with a period of 9. This means that when 1142857143 is multiplied by any integer from 1 to 9, the resulting product will contain the same digits as 1142857143, but in a different order. For example, multiplying 1142857143 by 2 results in 2285714286, which contains the same digits as 1142857143. This property makes 1142857143 an interesting subject of study in number theory and recreational mathematics. The discovery of cyclic numbers like 1142857143 has contributed to the development of various mathematical concepts and techniques.
