Math Question: What is the sum of the digits of the number 4087 multiplied by 3, divided by the square of the sum of the number's digits?

To find the sum of the digits of 4087, we have 4 + 0 + 8 + 7 = 19. Multiplying this sum by 3 gives us 57. Now, let's calculate the square of the sum of its digits, which is (19)^2 = 361. Dividing 57 by 361 gives us approximately 0.157. Hence, the answer is 0.157.

What is the sum of the digits of the number obtained by squaring the number 4087?

To obtain the square of 4087, we multiply it by itself: 4087 x 4087 = 16,699,969. Now, adding the individual digits of this result gives us: 1 + 6 + 6 + 9 + 9 + 9 + 6 + 9 = 55. Hence, the sum of the digits of 4087 squared is 55.

What is the largest prime factor of the number 4087?

To find the largest prime factor of 4087, we start by dividing it by the smallest prime number, which is 2. However, 4087 is not divisible by 2. Next, we try dividing it by the next prime number, 3. Dividing 4087 by 3 gives us a quotient of 1362 with a remainder of 1. Continuing in this manner, we try dividing by 5, 7, 11, 13, and so on until we reach the square root of 4087. None of these prime numbers divides 4087 evenly, indicating that 4087 is a prime number itself. Therefore, the largest prime factor of 4087 is 4087.
