The mystery is this: first, take any three digit number, where the first and last digits differ by two or more and reverse the number to produce a new one. Then subtract the smaller from the larger producing another new number. If you reverse this number and this time add the two, the result will always be 1089.
Trick 8: Think of a 3 digit number
Pick a 3-digit number with all three digits different. Reverse the digits and subtract to get another 3-digit number. Reverse the digits of the difference and add it to the difference. Your sum will be 1089.
Write down a three-digit number whose digits are decreasing. Then reverse the digits to create a new number, and subtract this number from the original number. With the resulting number, add it to the reverse of itself. The number you will get is 1089!
Mentalists guess numbers using a number of methods to either see through to the answer that is written and placed in a special envelope, or they use something called a Swami pencil to write it after you've written yours. Here, we'll dive a little deeper into how they do what they do.
Yes, 1089 is a perfect square, as it can be expressed in the form of the product of two equal integers. (i.e) 1089 = 33×33.
There are overall 9 factors of 1089 among which 1089 is the biggest factor and 1, 3, 9, 11, 33, 99, 121, 363, 1089 are positive factors. The Prime Factors of 1089 are 3 × 11 and its Factors in Pairs are (1, 1089), (3, 363), (9, 121), (11, 99), (33, 33).
To physicists, 137 is the approximate denominator of the fine-structure constant (1/137.03599913), the measure of the strength of the electromagnetic force that controls how charged elementary particles such as the electron and muon interact with photons of light, according to the National Institute of Standards and ...
The number 6174 is known as Kaprekar's constant after the Indian mathematician D. R. Kaprekar.
The first few weird numbers are 70, 836, 4030, 5830, 7192, 7912, 9272, 10430, ... (OEIS A006037). An infinite number of weird numbers are known to exist, and the sequence of weird numbers has positive Schnirelmann density.
Missing numbers are the numbers that got missed in the given series of numbers with similar differences among them. The process of writing the missing numbers is termed as finding similar changes between those numbers and filling their missing values in their specific series and places.
Discovered by mathemagician Srinivas Ramanujan, 1729 is said to be the magic number because it is the sole number which can be expressed as the sum of the cubes of two different sets of numbers. Ramanujan’s conclusions are summed up as under: 1) 10 3 + 9 3 = 1729 and 2) 12 3 + 1 3 = 1729.
The programme counted down the fifty greatest magic tricks, as voted for by members of The Magic Circle. The illusion at number one was Death Saw by David Copperfield.

Factors of 1111: 1, 11, 101, 1111. Factor pairs: 1111 = 1 × 1111 or 11 × 101.
The factors of 2058 are 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294, 343, 686, 1029, 2058 and its negative factors are -1, -2, -3, -6, -7, -14, -21, -42, -49, -98, -147, -294, -343, -686, -1029, -2058.
12 is not a perfect number because the sum of its factors, 1+2+3+4+6 is greater than 12. Numbers like 12 are known as abundant numbers .
14 is an even number, a composite number, and a rational number, but not a perfect number. The factors of 14 are 1, 2, 7, and 14. The sum of 1, 2, and 7 is 10. Since the sum of the factors other than 14 itself are not equal to 14, 14 is not a perfect number.
A perfect number is a rare number. To date, only 51 of them have been discovered. There are only three perfect numbers less than 1000: 6, 28, and 496.
1089 is widely used in magic tricks because it can be "produced" from any two three-digit numbers. This allows it to be used as the basis for a Magician's Choice.
