Math Question: Find the sum of the digits in the number 6438, then divide the result by the product of the second and third digits, and finally multiply the quotient by the fourth digit. What is the final result?

To find the sum of the digits in 6438, we add 6+4+3+8 which equals 21. Dividing 21 by the product of the second and third digit (4*3=12) gives us a quotient of 1.75. Multiplying this quotient by the fourth digit 8 gives us a final result of 14. Therefore, the answer is 14.

Question: What is the sum of the digits of the number 6438 when each digit is raised to the power of its corresponding position?

To calculate the sum, we raise each digit to the power of its position and then sum them up: 6^1 + 4^2 + 3^3 + 8^4 = 6 + 16 + 27 + 4096 = 4135. The sum of the digits of the number 6438, where each digit is raised to the power of its position, is 4135.

What are the prime factors of the number 6438? Calculate their sum and find their product.

To find the prime factors of 6438, we divide it by the smallest prime number, 2, obtaining 3219. Applying the same step again, we divide by 3, resulting in 1073. The next prime factor is 13, yielding a quotient of 82. Finally, dividing by 2, we get the last prime factor, 41. The prime factors of 6438 are 2, 3, 13, and 41. The sum of these prime factors is 2 + 3 + 13 + 41 = 59. The product of these prime factors is 2 * 3 * 13 * 41 = 12,474. Therefore, 6438 has four prime factors with a sum of 59 and a product of 12,474.
