Math question: What is the least common multiple (LCM) of 9918 and 7?

To find the LCM of 9918 and 7, we can factorize 9918 as 2 × 7 × 7 × 101. Comparing the prime factorization with 7, we see that the LCM should include both prime factors, 2 and 101, and since 7 already appears twice, we take the maximum exponent for each prime factor. Hence, the LCM of 9918 and 7 is 2 × 7 × 7 × 101 = 98 × 101 = 9898. The LCM represents the smallest common multiple of both numbers. In this case, 9898 is the smallest number that is divisible by both 9918 and 7 without leaving any remainder.

Math question: What is the value of 9918 when multiplied by the sum of its digits divided by the product of its digits?

To find the sum of the digits, we have 9 + 9 + 1 + 8 = 27. The product of the digits is 9 * 9 * 1 * 8 = 648. So, the expression becomes 9918 * (27 / 648). Simplifying this further gives us 9918 * 0.0416667. By performing the calculation, we find that this is equal to 412.93501. Therefore, the value of 9918 when multiplied by the sum of its digits divided by the product of its digits is approximately 412.93501.

Math Question: What is the sum of the first 50 positive multiples of 9918 that are divisible by 8?

To find the sum of the first 50 positive multiples of 9918 divisible by 8, we observe that 9918 is not divisible by 8, but its next multiple, 9920, is divisible by 8. So, the sequence starts with 9920, and we can generate the subsequent numbers by adding 8 repeatedly. The sum of an arithmetic sequence is given by the formula S = (n/2)(a + l), where n is the number of terms, a is the first term, and l is the last term. Using this formula, we have n = 50, a = 9920, and l = 9920 + (50-1)8 = 10312. Plugging in these values, the sum S = (50/2)(9920 + 10312) = 1311600. Therefore, the sum of the first 50 positive multiples of 9918 divisible by 8 is 1,311,600.
