Math question: What is the smallest prime number that divides the number 858?

To find the smallest prime number that divides 858, we first list out the prime numbers: 2, 3, 5, 7, 11, 13, 17, etc. Dividing 858 by 2, we get 429. Continuing to divide by 2, we get 214, then 107, which is prime. So the smallest prime number that divides 858 is 107.

Math question: What is the sum of 858, its square root (rounded to the nearest whole number), and 1/10th of its cube?

For the number 858, we can find the square root by using a calculator, which is approximately 29.27 (rounded to two decimal places). Rounding this value to the nearest whole number gives 29. Adding the square root of 858 to itself gives a sum of 29 + 29 = 58. To find 1/10th of 858 raised to the power of 3 (or the cube of 858), we can calculate 858^3 = 641,211,912.5 (rounded to one decimal place). Now, taking 1/10th of this value, we get 641,211,912.5 ÷ 10 = 64,121,191.25 (rounded to two decimal places). Finally, adding 858, its square root (29), and 1/10th of its cube (64,121,191.25), we get 858 + 29 + 64,121,191.25 = 64,122,078.25. Therefore, the answer is 64,122,078.25.

Math question: What is the largest prime factor of the number 858?

To find the largest prime factor of 858, we start by listing the prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, and so on. We divide 858 by each prime number, starting with the smallest. When we divide 858 by 2, we get 429 as the quotient. We continue dividing by 2 until we can no longer divide evenly. Next, when we divide 429 by 3, we obtain 143. Dividing 143 by 11, we get 13 as the quotient. Since 13 is a prime number, it is the largest prime factor of 858. Thus, 13 is the answer.
