3 Digit Number Trick

, , Leave a comment

Think of any 3 digit number. Multiply the number by 7, the result by 11 and then the result by 13. You will get the product as a repetition of the same 3 digit number. For example, 121 is our number. 121*7=847, now multiply the product by 11, 847*11=9317. Multiply this product with 13, 9317*13=121121. The answer is a repetition of the digits of our original number.
