Math question: What is the sum of the digits in the number 7387?

To find the sum of the digits in the number 7387, we add the digits together: 7 + 3 + 8 + 7 = 25.

What is the largest prime number smaller than 7387?

In order to find the largest prime number smaller than 7387, we start by checking if 7387 is prime. To do this, we divide 7387 by all prime numbers up to its square root (i.e., 86, which is the nearest integer square root of 7387). After dividing, we find that 7387 is divisible by 7 and 29. Therefore, it is not prime. So, we decrement 7387 by 1 and check if the resulting number (7386) is prime. Again, we divide it by all prime numbers up to its square root. In this case, 7386 is divisible by 2, 3, 7, 13, and 29. Hence, we continue decrementing until we find a prime number. After some iterations, we discover that 7379 is the largest prime number smaller than 7387. Thus, the answer is 7379.

Question: What is the sum of the individual digits in the number 7387?

To find the sum of the individual digits in the number 7387, we add the values of each digit together. 7 + 3 + 8 + 7 = 25. Therefore, the sum of the digits in the number 7387 is 25. The individual digits are 7, 3, 8, and 7, and their sum is 25.
