Math Question: If 357 is multiplied by the sum of its digits, divided by the product of its digits squared, and the result is divided by twice the square root of the greatest prime factor of 357, what is the final value?

To find the result, let's first break down 357. The sum of its digits is 3+5+7=15. The product of its digits squared is (3*3) * (5*5) * (7*7) = 1323. The greatest prime factor of 357 is 7. Therefore, twice the square root of 7 is 2 * √7 = 5.30 (approx). Now, multiplying the sum of digits (15) by 357 gives 357*15 = 5355. Then divide it by the product of its digits squared (1323), resulting in 5355/1323 = 4.05 (approx). Finally, dividing this by twice the square root of the greatest prime factor (5.30), gives 4.05/5.30 = 0.77 (approx). Hence, the final value is approximately 0.77.

Math question: What is the sum of the digits in the number 357?

To find the sum of the digits in the number 357, you need to add the individual digits together. So, 3 + 5 + 7 = 15. The sum of the digits in number 357 is 15. This is obtained by adding the digits 3, 5, and 7.

Math question: What is the largest prime factor of 357?

To find the largest prime factor of 357, we start by dividing it by the smallest prime number, 2, yielding 357 ÷ 2 = 178 remainder 1. Since 178 is even, we continue dividing by 2: 178 ÷ 2 = 89, a prime number. Hence, 89 is the largest prime factor of 357.
