Math Question: What is the smallest prime number greater than 7100?

The smallest prime number greater than 7100 is 7109. Prime numbers are positive integers greater than 1 that have no other positive divisors except 1 and themselves. To find the answer, we start checking divisibility for numbers greater than 7100. By dividing 7109 by 2, 3, 4, 5, 6, 7, and 8, we see that none of these integers divide evenly into 7109. Therefore, it is not divisible by any number smaller than itself, making it prime.

What is the sum of the digits of the number 7181?

The sum of the digits of 7181 is 17.

Math question: If 7181 is multiplied by a certain number and then divided by another number, the result is equal to 2356. What are those two numbers?

Let's call the unknown number to be multiplied by 7181 as 'x', and the number to be divided by as 'y'. We can set up the equation: (7181 * x) / y = 2356. To solve for 'x' and 'y', we can rewrite the equation as: 7181 * x = 2356 * y. Now, let's find the prime factors of both sides of the equation. The prime factorization of 7181 is 41 * 175. On the other hand, the prime factorization of 2356 is 2^2 * 7 * 7 * 13. Comparing the prime factors, we see that no prime factors are common between the two sides of the equation. Therefore, it is not possible to find 'x' and 'y' such that their multiplication and division will result in 2356 when multiplied by 7181. Hence, there are no solutions to this equation.
