Math question: If the number 1143 is divided by the product of 7 and 3, what is the remainder when divided?

To find the remainder, we divide 1143 by (7 x 3) = 21. When 1143 is divided by 21, the quotient is 54 with a remainder of 9. Therefore, the remainder when 1143 is divided by (7 x 3) is 9.

Math Question: What is the sum of all the prime factors of the number 1143?

To find the prime factors of 1143, we can begin by dividing it by the smallest prime number, 2, which gives us 571. Now, 571 is a prime number itself. The sum of all prime factors of 1143, therefore, is 2 + 571 = 573.

Question: What is the least positive integer greater than 1143 that is divisible by both 3 and 7?

To find the solution, we need to find the smallest multiple of 3 that is greater than 1143, and then check if it is divisible by 7. Dividing 1143 by 3 gives us 381 with a remainder of 0. The next multiple of 3 is 384. Checking if 384 is divisible by 7, we find that it is not, as its digits do not add up to a multiple of 7. So, we need to keep looking. Adding 3 to 384 gives us 387, which is still not divisible by 7. We continue this process until we find a multiple divisible by both 3 and 7. After some calculations, we find that the least positive integer greater than 1143 divisible by both 3 and 7 is 1146. Verification: Dividing 1146 by 3, we get 382 with a remainder of 0. Dividing the same number by 7, we also get 163 with a remainder of 0. This confirms that 1146 is indeed the correct solution to the question.
