Math question: What is the largest prime factor of the number 8420?

To find the largest prime factor of 8420, we begin by dividing it successively by prime numbers. First, we check if it's divisible by 2, and indeed 8420 ÷ 2 = 4210. We continue the process and divide 4210 by 2, obtaining 2105. Proceeding further, we observe that 2105 is divisible by 5, yielding 421. Since 421 is a prime number, it cannot be divided further. Thus, the largest prime factor of 8420 is 421. Explanation: Prime factorization is the process of decomposing a number into its prime factors. In this case, the prime factorization of 8420 is 2 × 2 × 5 × 421. The largest of these prime factors is 421.

Math question: What is the sum of the digits in the number 8420?

To find the sum of the digits in 8420, we add the individual digits: 8 + 4 + 2 + 0 = 14.

Question: What is the product of 8420 when divided by 13, multiplied by 17, subtracted by 15, and finally divided by 2, rounded to the nearest whole number?

To calculate the product, we first divide 8420 by 13, resulting in approximately 648. Then, we multiply 648 by 17, which equals approximately 11016. Subtracting 15 from 11016 gives us approximately 11001. Finally, dividing 11001 by 2 gives us approximately 5500.5. Rounding this to the nearest whole number, we get the final answer of 5501.
