Math Question: What is the smallest prime factor of the number 1272?

To find the smallest prime factor of 1272, we divide it by prime numbers starting from 2. Dividing 1272 by 2 gives us 636, which is an even number. Continuing this process, dividing it by 3 gives 212, which is still divisible. If we divide it by 4, we get 318, not a factor either. Dividing by 5 gives 254, which is not divisible. However, dividing by 6 gives 212, which means the smallest prime factor is 2. So, the smallest prime factor of 1272 is 2.

Math question: If 1272 is divided by the sum of its digits, what is the quotient?

To find the sum of the digits, we add 1 + 2 + 7 + 2 = 12. Now, let's divide 1272 by 12. The quotient is 106. Therefore, when 1272 is divided by the sum of its digits, the quotient is 106.

Math Question: What is the square root of the sum of 1272 multiplied by its double, divided by the difference between 1272 and its square?

Considering the given number 1272, its double is 2544. The square of 1272 is 1,618,784. The sum of 1272 and 2544 is 3,816. The difference between 1272 and its square is 1,617,512. Dividing 3,816 by 1,617,512 gives a very small decimal value representing the ratio. Lastly, taking the square root of this ratio, we obtain an even smaller decimal value. Therefore, the answer to the math question is a very small non-zero decimal value, suggesting a weak correlation or negligible impact of these operations on the number 1272.
