Math question: What is the product when the largest prime factor of 1918 is multiplied by its smallest prime factor?

To find the largest prime factor of 1918, we factorize it as 1918 = 2 × 959. Hence, the largest prime factor is 959 itself. Similarly, the smallest prime factor is 2. So the product of the largest and smallest prime factors is 959 × 2 = 1918. The number 1918 lies between two historical years: the end of World War I (1918) and the beginning of the Spanish Flu pandemic (1917-1920), emphasizing the significance of those times and the immense impact they had on humanity.

Math Question: Consider the number 1918. If we divide it by 17, add 6, and then multiply by 9, what is the result?

To find the result, we start by dividing 1918 by 17, which gives us 113. Next, we add 6 to this quotient, resulting in 119. Finally, we multiply this sum by 9, giving us the final result of 1071. Therefore, when we divide 1918 by 17, add 6, and multiply by 9, the result is 1071. This process allows us to manipulate the given number and perform arithmetic operations to obtain an answer.

Question: Given the number 1918, find the sum of the digits squared, multiply by the difference between the first and last digits, and then add the product of the second and third digits. What is the result?

To find the sum of the digits squared, add 1² + 9² + 1² + 8² = 1 + 81 + 1 + 64 = 147. The difference between the first and last digits is 1 - 8 = -7. The product of the second and third digits is 9 * 1 = 9. Adding these together, we have 147 + (-7) + 9 = 149. Therefore, the result of the calculation is 149.
