Math question: Can you find a factor of 7943 besides 1 and 7943?

To determine if there is a factor of 7943 besides 1 and 7943, we need to check for any divisors between 2 and the square root of 7943 (approximately 89). We divide 7943 by each number and see if the remainder is 0. After checking all numbers from 2 to 89, no divisors are found. Therefore, 7943 is a prime number.

Question: What is the product of the tens digit and the sum of the digits of the number 7943?

To find the product, we first need to determine the sum of the digits in 7943. The sum is calculated by adding each digit: 7 + 9 + 4 + 3 = 23. Next, we multiply the tens digit (9) by the sum we just found: 9 x 23 = 207. Therefore, the product of the tens digit and the sum of the digits of the number 7943 is 207.

Math Question: If the number 7943 is multiplied by 3 and then divided by 17, what is the remainder when the result is divided by 11?

When the number 7943 is multiplied by 3, we get 23829. Now, dividing 23829 by 17 gives us a quotient of 1401 with a remainder of 12. Therefore, the remainder when the result is divided by 11 is 1.
