Math Question: What is the maximum prime number less than 1393?

To find the maximum prime number less than 1393, we start by checking if 1393 is prime. Dividing it by numbers up to its square root (37), we find it is not divisible by any of them. Now, we step backward checking prime numbers less than 1393. Starting from 1387, we divide it by primes decreasingly (1381, 1373, 1367, etc.) until we reach 2, which is the largest prime number less than 1393 as no prime numbers smaller than it can divide it perfectly. Therefore, the maximum prime number less than 1393 is 1381.

Math question: If 1393 is divided by the sum of its digits, what is the quotient obtained?

To find the quotient, we first add the digits of 1393: 1 + 3 + 9 + 3 = 16. Now, we divide 1393 by 16: 1393 ÷ 16 = 87.06 (rounded to 2 decimal places). Therefore, the quotient obtained when 1393 is divided by the sum of its digits is approximately 87.06.

Math question: What is the sum of the digits in the number 1393?

To find the sum of the digits in the number 1393, we add the individual digits together: 1 + 3 + 9 + 3 = 16.
