What is the sum of the digits in 3872?

To find the sum of the digits in 3872, we add the individual digits: 3 + 8 + 7 + 2 = 20. The sum is 20. The process involves isolating each digit in the number (3, 8, 7, 2) and then adding them together. This method can be used to find the sum of the digits in any number.

Question: What is the smallest prime number that can be evenly divided by 3872 and is also a multiple of 9?

To find the smallest prime number that satisfies both conditions, we need to analyze the prime factorization of 3872. First, we prime factorize 3872 as 2^5 * 11^2. However, from the second condition, we must take into account that the prime factorization should also include a factor of 9, which is 3^2. Notice that 3^2 * 2^5 * 11^2 = 3^2 * (2 * 2^4) * (11 * 11) = (3 * 11 * 2^2)^2. Thus, the prime number that can be evenly divided by 3872 and is a multiple of 9 is (3 * 11 * 2^2), which is 132.

What is the sum of the first 10 even numbers greater than 3872? (3874 + 3876 + 3878 + 3880 + 3882 + 3884 + 3886 + 3888 + 3890 + 3892 = ?)

The sum of the first 10 even numbers greater than 3872 is 38870.
