Math question: What is the sum of all the prime factors of the number 1904?

To find the prime factors of 1904, we begin by factoring it as follows: 1904 = 2 * 2 * 2 * 2 * 7 * 17. The prime factors are 2, 7, and 17. Let's calculate their sum: 2 + 2 + 2 + 2 + 7 + 17 = 32. Therefore, the sum of all the prime factors of 1904 is 32. Prime factors play a crucial role in number theory, cryptography, and prime factorization algorithms. They represent the prime numbers that divide a given number without leaving a remainder. Discovering the prime factors of a composite number helps in understanding its unique characteristics and can be useful in various mathematical applications.

Math question: How many different 4-digit numbers can be formed using the digits 1, 0, 9, and 4 without repetition?

To find the number of different 4-digit numbers without repetition, we can use the concept of permutations. Since we have 4 unique digits (1, 0, 9, and 4), the first digit can be any of the 4 choices. Once the first digit is chosen, we have 3 remaining choices for the second digit, 2 choices for the third digit, and only 1 choice remains for the last digit. Hence, the total number of different 4-digit numbers is given by 4 × 3 × 2 × 1 = 24. Therefore, there are 24 different 4-digit numbers that can be formed using the digits 1, 0, 9, and 4 without repetition.

Math question: If the number 1904 is multiplied by the sum of its digits, what is the result?

To find the sum of the digits of 1904, we add 1+9+0+4=14. Now, multiply 1904 by 14 to get the result. 1904 × 14 = 26656. Hence, when multiplied by the sum of its digits, the number 1904 yields 26656.
