Math question: What is the sum of all the odd numbers between 1 and 3447?

To find the sum, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. Since 3447 is an odd number, the last term is also an odd number. Firstly, let's find the number of terms. We know that the sequence of odd numbers is an arithmetic sequence with a common difference of 2. So, we can use the formula for the nth term: an = a + (n-1)d, where an is the nth term, a is the first term, and d is the common difference. By setting an = 3447 and solving for n, we get n = (3447 - 1)/2 = 1723. Thus, we know there are 1723 terms. The first term, a, is 1, and the last term, l, is 3447. Plugging these values into the sum formula, we have Sn = (1723/2)(1 + 3447) = 1487279. Therefore, the sum of all odd numbers between 1 and 3447 is 1,487,279.

Question: What is the largest prime factor of the number 3447?

To find the largest prime factor of 3447, we can start by dividing it by the smallest prime number, 2. However, we observe that 3447 is an odd number, so it is not divisible by 2. Proceeding further, we divide 3447 by 3 and find that it is divisible, resulting in 1149. Now we divide 1149 by 3 again and get 383, which is a prime number. Hence, the largest prime factor of 3447 is 383.

Math question: How many times does the digit 4 appear when counting from 1 to 3447 inclusive?

To find the occurrences of the digit 4, we analyze each place value separately. In the units place, the digit 4 appears once every ten numbers (4, 14, 24,..., 3444), so it occurs 345 times. In the tens place, there are 10 choices for the digit 4 (40, 41, ..., 49) for each hundred, giving us 34 choices, thus it occurs 34 × 10 = 340 times. In the hundreds place, the digit 4 appears 3 times for each thousand, resulting in 3 × 10 = 30 times. Therefore, from 1 to 3447, the digit 4 appears 345 + 340 + 30 = 715 times.
