Math question: What is the sum of the digits in the number 423?

To find the sum of the digits in 423, we can break it down and add the individual digits together. Starting from the right, we have 3 + 2 + 4 = 9. Hence, the sum of the digits in the number 423 is 9. This can be illustrated by understanding each digit's positional value: the 3 represents 3 units, the 2 represents 20 (2 tens), and the 4 represents 400 (4 hundreds). Adding these values together results in 423. So, when adding the individual digits together, we obtain the sum of 9.

Math question: Find a positive integer, which, when multiplied by 423, results in a product with exactly five 0s at the end.

To determine a positive integer that multiplies with 423 to give a product with five 0s at the end, we need to find a number that has a factorized form with at least five pairs of 2 and 5. 423 is not divisible by 5, which means the final product must be even. Thus, we need to find a multiple of 423 that includes at least five powers of 2 but not 10 (since 10 = 2 x 5). The prime factorization of 423 is 3 x 3 x 47. Therefore, to form a number with five factors of 2, we need to include three pairs of 2s. A suitable integer would be 423 x (2^3) = 423 x 8 = 3384. This results in a product with five 0s at the end when multiplied by 423. Hence, the positive integer is 3384.

Math Question: The number 423 is divisible by what positive integers?

The number 423 is divisible by 1, 3, 7, 9, 47, 141, 329, and 423. To find these divisors, we can perform factorization. Starting with the prime factorization of 423 as 3 × 3 × 47, we can obtain divisors by finding all possible combinations of these prime factors. The divisors are obtained through the following combinations: 1 × 423 = 423 47 × 9 = 423 3 × 141 = 423 329 × 1 = 423 7 × 61 = 423 141 × 3 = 423 9 × 47 = 423 423 × 1 = 423 Thus, the positive divisors of 423 are 1, 3, 7, 9, 47, 141, 329, and 423. These are the numbers that divide 423 without leaving a remainder.
