What is Smith number in Python?
A Smith Number is a composite number whose sum of digits is equal to the sum of digits in its prime factorization.
How do I find my Smith Number?
Steps to Find Smith Number
- Read or initialize a number from the user.
- Find the sum of its digits.
- Find the prime factors of the given number.
- Determine the sum of digits of its prime factors.
- Compare the sum of digits with the sum of digits of its prime factors. If they are equal, the given number is a smith.
How is Smith number calculated?
Smith Numbers. A Smith number is a composite number, the sum of whose digits equals the sum of the digits of all its prime factors. The smallest Smith number is 4 = 2×2. The sum of the digits of 4 is 4, and The sum of digits of its prime factors is 2 + 2 = 4.
How do you check whether a number is power of 4 or not?
A simple method is to take a log of the given number on base 4, and if we get an integer then the number is the power of 4. 2. Another solution is to keep dividing the number by 4, i.e, do n = n/4 iteratively.
How do you check whether a number is power of 3 or not?
Observation 2 : If a number ends with one of these 4 digits, we only have to check the powers of three which would guarantee a number ending with that last digit. For example, if a given number ends with 1, it must be a 4th or 8th or 12th and so on power of three, if at all.
What is Smith number in computer?
A Smith number is a composite number whose sum of digits equals to the sum of digits of its prime factors, excluding 1. It is also known as a joke number. It is a sequence of OEIS A006753.
What is Smith number with example?
A Smith number is a composite number, the sum of whose digits equals the sum of the digits of all its prime factors. The smallest Smith number is 4 = 2×2. The sum of the digits of 4 is 4, and The sum of digits of its prime factors is 2 + 2 = 4.
What is an integer power of 4?
The sequence of fourth powers of integers (also known as biquadrates or tesseractic numbers) is: 0, 1, 16, 81, 256, 625, 1296, 2401, 4096, 6561, 10000, 14641, 20736, 28561, 38416, 50625, 65536, 83521, 104976, 130321, 160000, 194481, 234256, 279841, 331776, 390625, 456976, 531441, 614656, 707281, 810000.
Which is an example of a Smith number?
A Smith Number is a composite number whose sum of digits is equal to the sum of digits in its prime factorization. Examples: Input : n = 4 Output : Yes Prime factorization = 2, 2 and 2 + 2 = 4 Therefore, 4 is a smith number Input : n = 6 Output : No Prime factorization = 2, 3 and 2 + 3 is not 6.
Which is the first step in the algorithm?
So now lets see the Flowchart and Pseudocode for better understanding. The first step in the algorithm is taking a number as an input from User. Let’s say user enters value 6. So 6 will be stored inside variable “number”. Now the next step in algorithm (i.e number%2==0), in this step (number%2) returns the remainder after dividing number by 2.
What does it mean to write an algorithm?
Writing the Algorithm. A finite set of steps that must be followed to solve any problem is called an algorithm. Algorithm is generally developed before the actual coding is done. It is written using English like language so that it is easily understandable even by non-programmers.
