What is the greatest prime factor of the number 4045?

To find the greatest prime factor of 4045, we start by dividing it by the smallest prime number, 2. The result is not a whole number. Next, we divide by 3, and we get 1348.333. Continuing, we divide by 5, resulting in 269.666. Then, we divide by 7, yielding 57.857. By dividing 4045 by 11, we arrive at 368.636. However, when dividing by 13, we get 310.385. But we find that dividing by 17 gives us an exact whole number of 238.529. Continuing the process, dividing by 19 yields 212.368, and dividing by 23 gives 175.869. Finally, dividing by 29 results in 139.138. Therefore, the greatest prime factor of 4045 is 29.

The four-digit number 4045 is divisible by 5. How many positive integers less than 1000 are also divisible by 5 but not equal to 4045?

To find the number of positive integers in the form of 5k, where k is a positive integer less than 200, we use the formula (Last Term - First Term) / Common Difference + 1. The last term would be 5 * 199 = 995, the first term is 5 * 1 = 5, and the common difference is also 5. Applying the formula, we get (995 - 5) / 5 + 1 = 199 - 1 + 1 = 199. However, this count includes the number 4045, so we subtract 1. Thus, the number of positive integers divisible by 5 but not equal to 4045 is 199 - 1 = 198.

Find the sum of the prime factors of the number 4045.

To find the prime factorization of 4045, first divide it by the smallest prime number, which is 5. This yields 809 as the quotient. Next, divide 809 by the next smallest prime, which is 11. The quotient is 73, which is a prime number itself. Therefore, the prime factorization of 4045 is 5 * 11 * 73. Now, to find the sum of these prime factors, add them up: 5 + 11 + 73 = 89. Hence, the sum of the prime factors of 4045 is 89.
