Math Question: What is the sum of the prime factors of the number 3863?

To determine the prime factors of 3863, we start by dividing it successively by prime numbers. Since dividing 3863 by 2 yields a fractional result, we move on to the next prime, 3. Upon dividing 3863 by 3, we obtain 1287. Dividing 1287 by 3 again gives 429, and dividing 429 by 3 once more results in 143. Finding that 143 cannot be divided by 3, we move on to the next prime: 5. Dividing 143 by 5 provides 28 remainder 3. As 3 does not divide evenly into 28, we try the next prime, 7, which also doesn't cleanly divide 28. Finally, we test division by 11, which reveals that 28 can be divided by 11 with a remainder of 7. Now, we have reached a prime factor since 7 cannot be divided any further. Consequently, the prime factors of 3863 are 3, 3, 7, and 11. Summing these primes, we get the answer 3 + 3 + 7 + 11 = 24.

Question: What is the sum of the digits of the number 3863, when it is multiplied by the value obtained by subtracting 1279 from the product of the first two digits multiplied by the last two digits?

To find the sum of the digits of 3863, we first calculate the value obtained by subtracting 1279 from the product of 38 (the first two digits) and 63 (the last two digits) which gives us 38 × 63 - 1279 = 2394. Now, let's calculate the sum of the digits of 2394. The digit sum of 2394 is found by adding the individual digits, which are 2, 3, 9, and 4. Thus, the sum is 2 + 3 + 9 + 4 = 18. Therefore, the sum of the digits of 3863, when multiplied by the value obtained by subtracting 1279 from the product of the first two digits multiplied by the last two digits, is equal to 18 × 2394 = 43,092.

Question: If 3863 is multiplied by 9, divided by 13, and then rounded to the nearest whole number, what is the result?

To find the result, we'll calculate (3863 * 9) / 13 ≈ 2670. Depending on the rounding approach, this could be rounded to either 2670 or 2671. Since it needs to be rounded to the nearest whole number, we consider the decimal value. Since 2670.230 imply a decimal value below 0.5, we round down to 2670. Hence, the result is 2670.
