Math Question: What is the sum of the first 10 multiples of 620?

To find the sum of the first 10 multiples of 620, we need to calculate the arithmetic sequence. The first term is 620, and the common difference is also 620. The formula for the sum of an arithmetic sequence is S_n = [n/2][(2a + (n-1)d)], where S_n is the sum, n is the number of terms, a is the first term, and d is the common difference. Plugging in the values, we get S_10 = [10/2][(2*620 + (10-1)*620)]. Simplifying further, S_10 = [5][(1240 + 9*620)] = [5][(1240 + 5580)] = [5][(6820)] = 34100. Therefore, the sum of the first 10 multiples of 620 is 34100.

What is the largest prime factor of the number 620?

To find the largest prime factor of 620, we can start by dividing it by 2, as it is an even number. 620 divided by 2 leaves us with 310. Continuing the process, we divide 310 by 2, giving us 155. Observing that 155 is an odd number, we can try dividing it by the next prime number, 3. However, it is not divisible by 3. Further division shows that 155 can be divided by 5, leaving us with 31. Finally, 620 can be expressed as 2 × 2 × 5 × 31. Therefore, the largest prime factor of 620 is 31.

Math question: If you multiply the number 620 by 2, then add 400, subtract 100, and finally divide by 5, what is the result?

To solve this, we follow the order of operations. First, we double 620 to get 1240. Next, we add 400 to obtain 1640. Then, we subtract 100, giving us 1540. Finally, we divide by 5, leading to a final answer of 308. Therefore, after these operations, the result of starting with 620 and following the given calculations is 308.
