Math question: Find the largest three-digit number that is divisible by 3, 4, and 6.

To find the largest three-digit number divisible by 3, 4, and 6, we need to find their least common multiple (LCM). First, LCM of 3 and 4 is 12. Now, we need to find the LCM of 12 and 6, which is 12. To determine how many times 12 goes into 1000 (the largest three-digit number), we divide 1000 by 12. The quotient is 83 with a remainder of 4. We subtract 4 from 1000 to get the largest three-digit number divisible by 12. Thus, the largest three-digit number divisible by 3, 4, and 6 is 996.

Question: The number 1386 is a multiple of 2 and lies between two consecutive perfect squares. What are these perfect squares?

To find the perfect squares, let's take the square root of 1386, which is approximately 37.24. Now we know that the perfect squares before and after 1386 are 37^2 = 1369 and 38^2 = 1444, respectively. Thus, 1386 lies between 1369 and 1444.

Math question: What is the largest prime factor of the number 1386?

To find the largest prime factor of 1386, we first need to factorize the number. 1386 can be expressed as 2 × 3 × 3 × 7 × 11. Now, to determine the largest prime factor, we search for the highest prime number among these factors: 11. Therefore, the largest prime factor of 1386 is 11. Prime factorization is a useful technique in number theory, helping us understand the fundamental building blocks of a number.
