Math question: What is the sum of the digits of the number 3881?

The sum of the digits of the number 3881 is 20. To find this, we add the individual digits together – 3 + 8 + 8 + 1 = 20. The sum of the digits can be helpful in various mathematical operations, including divisibility tests, calculating remainders, or even analyzing patterns within a number.

Question: What is the largest possible prime factor of 3881?

To find the largest prime factor of 3881, we start by dividing it by the smallest prime number, 2. However, 2 does not divide evenly into 3881. We continue dividing by subsequent prime numbers (3, 5, 7, ...) until we reach a prime number that divides evenly, or until we reach the square root of 3881. By trying all primes up to the square root of 3881 (approximately 62), we find that 3881 is a prime number itself. Therefore, the largest possible prime factor of 3881 is 3881 itself.

Question: What is the largest prime factor of 3881?

To find the largest prime factor of 3881, we start by dividing it by the smallest prime numbers. Dividing by 2, we get 3881/2 = 1940.5, so 2 is not a factor. Dividing by 3, we get 3881/3 ≈ 1293.67, so 3 is not a factor. Dividing by 5, we get 3881/5 = 776.2, so 5 is not a factor. Dividing by 7, we get 3881/7 ≈ 554.43, so 7 is not a factor. Continuing with this pattern, we try the next prime number, 11. Dividing by 11, we get 3881/11 = 353.72, which is not divisible by any smaller prime number. Therefore, the largest prime factor of 3881 is 3881 itself, as it has no prime factors other than 1 and itself.
