Math Question: What is the least common multiple of 2856 and 18?

To find the least common multiple (LCM), we analyze the prime factorization of both numbers. The prime factors of 2856 are 2, 2, 2, 3, 7, and 17, while the prime factors of 18 are 2 and 3. By taking the highest power of each prime factor from both numbers, we get 2^3, 3^1, 7^1, and 17^1. Multiplying these highest powers together, we get 8*3*7*17 = 2856. Thus, the least common multiple of 2856 and 18 is 2856 itself.

Math question: What is the product of the sum of the digits of the number 2856 and the cube root of 2856, rounded to the nearest thousandth?

To find the sum of the digits of 2856, we add 2 + 8 + 5 + 6 = 21. The cube root of 2856 is approximately 13.781. Multiplying the sum of the digits (21) by the cube root (13.781) gives us 289.101. Rounding it to the nearest thousandth, the answer is 289.000.

Math Question: What is the sum of the digits of the number 2856, when each digit is squared and multiplied by its respective place value?

To find the sum of the digits, we square each digit and multiply by its place value. The digit 2, in the thousandth place, squared and multiplied by 1000 gives 4000. The digit 8, in the hundredth place, squared and multiplied by 100 gives 6400. The digit 5, in the tens place, squared and multiplied by 10 gives 250. The digit 6, in the ones place, squared and multiplied by 1 gives 36. Summing these values (4000 + 6400 + 250 + 36) gives 10,686.
