# Se Citește Un Număr Natural N. Să Se Determine Numărul De Divizori Ai Oglinditului Lui N.

A natural number is any positive integer, or whole number, that is found in the set of natural numbers. It is common to want to determine the number of divisors a natural number has, or to find the mirror number of a natural number. This article will explain how to do both of these tasks.

## Determining the Number of Divisors of a Natural Number

To calculate the number of divisors of a natural number, first you must identify the factors of the natural number. Factors are any numbers that can be multiplied together to equal the natural number. To find the factors of the natural number, you must divide the natural number by all the numbers from 1 to the natural number itself. Any numbers that divide evenly into the natural number are factors. Once all of the factors have been found, you can count them up to find the total number of divisors.

## Calculating the Mirror Number of a Natural Number

The mirror number of a natural number is the number that is the same as the natural number, but written in reverse order. To calculate the mirror number of a natural number, you must first identify the digits of the natural number. You can do this by breaking the natural number into its individual digits. Once you have identified the digits, you must write them in reverse order to get the mirror number.

In conclusion, determining the number of divisors of a natural number and calculating the mirror number of a natural number are both relatively simple tasks. With a bit of practice, anyone can become an expert at these calculations.

In the world of mathematics, it is a common question to determine the number of divisors of a given integer. This article looks at the task of identifying the number of divisors of the oglinfited integer of a given number, n.

In mathematics, the oglinfited integer of a number refers to its reverse; for example, the oglinfited integer of 1234 would be 4321. The task at hand is to determine the number of divisors of the reverse of n.

To begin, the concept of divisors must be understood. Any number, x, is a divisor of a number, n, when x is a factor of n. That is, if n is evenly divided by x, then x is a divisor of n. For example, the divisors of 12 are 1,2,3,4,6, and 12, because 12 is divisible by each number.

To determine the number of divisors of the reverse of n, the prime factorisation of n must first be calculated. Prime factorisation is the decomposition of a number into its primes factors; that is, into its smallest composite parts. For example, 1284 has prime factorisation of 2x2x3x7x13, as each number is a prime factor of 1284.

After the prime factorisation of n has been calculated, the prime factorisation of the reverse of n is determined. Once the prime factorisations of both numbers have been established, the number of divisors of the reverse of n can be determined by multiplying the counts of each prime factor. This will give the final number of divisors of the reverse of n.

As an example, consider the number 1284. The prime factorisation of 1284 is 2x2x3x7x13; the prime factorisation of the reverse of 1284, 4821, is 7x7x13. The number of divisors of 1284 is 8: 1,2,4,7,13,14,28, and 91. The number of divisors of 4821 is thus 14: 1,7,13,49,91,133,343, 847, and 2401.

In conclusion, the number of divisors of the oglinfited integer of a given number, n, is determined by first finding the prime factorisation of n and then the prime factorisation of the reverse of n. By multiplying the counts of each prime factor, the number of divisors of the reverse of n can be computed.
