Question: In a three-digit number, each digit is one less than its place value. What is the greatest common divisor of all possible three-digit numbers satisfying this condition?

To find the numbers satisfying the condition, we look for three-digit numbers in the form of 100x + 10y + z, where x, y, and z are digits. According to the condition, x = 1, y = 0, and z = 2. Therefore, the number is 192. Since we are looking for the greatest common divisor (GCD) of all possible such numbers, we need to find the GCD of 192, 292, 392, ..., 992. Since the hundreds digit remains constant at 1 and tens place increases, all potential numbers will share a common factor, which is 1. Therefore, the GCD of all these numbers is 1.

What is the smallest prime number greater than 1927?

The smallest prime number greater than 1927 is 1931. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In this case, we need to find the first prime number after 1927. Starting from 1928, we can check if each number is divisible by any prime number less than or equal to its square root, as any composite number has at least one factor less than or equal to its square root. By applying this method, we find that 1931 is the first prime number after 1927.

Math question: What is the largest prime factor of the number 1927?

To find the largest prime factor of 1927, we start by dividing it by the smallest prime number, 2. However, 1927 is not divisible by 2. Next, we try dividing by 3, but it does not result in a whole number. We continue trying larger prime numbers until we find that 1927 is divisible by 17, resulting in 113 as the quotient. Now, we divide 113 by prime numbers, starting with 2 and ascending. None of the prime numbers divide it evenly. Consequently, we conclude that the largest prime factor of 1927 is 17.
