Find the sum of all the digits obtained by writing the number 8164, when taken two at a time and multiplied together, and then multiply the sum by the total number of combinations possible. Answer rounded to the nearest whole number.

To find the sum of the digits obtained by multiplying two at a time, we have 8x1 + 8x6 + 8x4 + 1x6 + 1x4 + 6x4 = 8 + 48 + 32 + 6 + 4 + 24 = 122. The total number of combinations possible is 4C2 = 6. Therefore, multiplying the sum by the number of combinations, we get 122 x 6 = 732. Rounded to the nearest whole number, the answer is 732.

Math question: What is the smallest prime number that divides evenly into the number 8164?

To find the prime factorization of 8164, we divide it successively by prime numbers starting from 2. We find that 8164 can be expressed as 2^2 * 2041. To determine the smallest prime number that divides it evenly, we observe that 2041 can be factored as 43 * 47. Hence, the prime factorization of 8164 is 2^2 * 43 * 47. Therefore, the smallest prime number that divides evenly into 8164 is 2, since 2^2 is part of its prime factorization.

What is the sum of the digits of the number 8164?

To find the sum of the digits, we add the individual digits of the number: 8 + 1 + 6 + 4 = 19.
