Math question: What is the sum of the digits of the number 4389?

To find the sum of the digits, we add each digit individually: 4 + 3 + 8 + 9 = 24. Therefore, the sum of the digits of the number 4389 is 24. Explanation: The number 4389 consists of 4, 3, 8, and 9 as its digits. By adding these digits, we determine their sum. Starting with 4, we add 3 to get 7. Then, adding 8 to 7 gives 15. Finally, adding 9 to 15 yields 24. Therefore, the sum of the digits of 4389 is 24.

Math question: What is the smallest positive integer that can be multiplied by 4389 to obtain a product that is a perfect square?

To find the smallest positive integer that can be multiplied by 4389 to obtain a perfect square product, we need to factorize 4389. It can be written as 3^2 * 487. For the product to be a perfect square, each prime factor's exponent needs to be an even number. Since the exponent of 3 is already even, we need to find the smallest multiple of 487 that is a perfect square. The prime factorization of 487 is 487^1. To ensure the exponent is even, we square this prime factorization, giving us 487^2. Therefore, the smallest positive integer to multiply by 4389 to obtain a perfect square is 487^2.

Math question: How many prime factors does the number 4389 have?

To find the prime factors of 4389, we start by dividing it by the smallest prime number, 2, but it's not divisible. Then we proceed with dividing it by 3, and it yields 1463. Continuing, we find that 1463 is divisible by 11, resulting in 133 as the quotient. Finally, dividing 133 by 7, we obtain 19. Since 19 is a prime number, we cannot divide it further. Therefore, the prime factorization of 4389 is 3 x 11 x 7 x 19. Therefore, it has 4 prime factors.
