Math Question: How many prime factors does the number 1639 have?

To find the prime factors of 1639, we start by dividing it by the smallest prime number, 2, which leaves us with 819. Continuing the process, we divide by 3, yielding 273. The next prime, 7, divides into 273, giving us 39, which further reduces to 13. As 13 is prime with no other smaller factors, we end our process, resulting in the prime factors of 1639 as 2, 3, 7, and 13. Therefore, the number 1639 has four prime factors.

Math question: What is the sum of the digits of the number 1639 when raised to the power of 3 and multiplied by 7 and then divided by the sum of the digits of 1639?

To find the sum of the digits of 1639, we add 1 + 6 + 3 + 9, which equals 19. If we raise 1639 to the power of 3, we get 4,468,332,119. Multiplying it by 7 gives us 31,278,324,833. Dividing this by the sum of the digits of 1639 (which is 19) yields approximately 1,644,120,253.

Math Question: What is the sum of the square of the hundreds digit, the cube of the tens digit, and the fourth power of the units digit of the number 1639?

To find the sum, first, extract the hundreds digit which is 1, square it: 1^2 = 1. Next, retrieve the tens digit which is 6, cube it: 6^3 = 216. Finally, obtain the units digit which is 9, raise it to the fourth power: 9^4 = 6561. Now, sum the results: 1 + 216 + 6561 = 6782. Hence, the sum of the square of the hundreds digit, cube of the tens digit, and fourth power of the units digit of 1639 is 6782.
