Math question: What is the smallest prime factor of the number 1845?

To find the smallest prime factor of 1845, we need to divide it by primes starting from 2. When dividing 1845 by 2, we get a quotient of 922.5 which is not a whole number. Continuing with 3, we divide 1845 by 3 and obtain a quotient of 615, which is a whole number. Therefore, the smallest prime factor of 1845 is 3.

Math question: If you divide an unknown number by 15, subtract 35 from the quotient, and multiply the result by 3, you get 1845. What is the unknown number?

To find the unknown number, let's set it as x. Therefore, the equation becomes 3((x/15) - 35) = 1845. Simplifying, we have (x/15) - 35 = 615. Let's isolate x next by adding 35 to both sides, resulting in (x/15) = 650. Next, multiply both sides by 15 to eliminate the fraction, yielding x = 9750. Therefore, the unknown number is 9750.

Math question: What is the largest prime factor of the number 1845?

To find the largest prime factor of 1845, we start by dividing it by 2, which leaves us with 922.5. Since 922.5 is not a whole number, we continue dividing by the next prime, which is 3. Dividing 922.5 by 3 gives us 307.5. Again, this is not a whole number, so we divide by the next prime, which is 5. We find that 307.5 divided by 5 is 61.5. Now dividing by 5, we get 61.5 / 5 = 12.3. Continuing this process, we divide by 3 to get 12.3 divided by 3 = 4.1. Finally, dividing by 41, we get 4.1 / 41 = 0.1, which is not a whole number. Therefore, the largest prime factor of 1845 is 41.
