Math question: If the number 5638 is divided by the number formed by writing its digits in reverse order, what is the result?

To find the result, we need to reverse the digits of the number 5638, which gives us 8365. Now, we divide 5638 by 8365. The quotient is 0 and the remainder is 5638. Therefore, the result of dividing 5638 by the number formed by reversing its digits is 0 remainder 5638.

Question: If I multiply the number 5638 by 5 and then add 42, what is the result?

To find the result, we multiply 5638 by 5, which gives us 28190. Then we add 42 to this product, resulting in a final answer of 28232.

Question: What is the smallest prime factor for the number 5638 that is greater than 2 and less than or equal to 100?

To find the smallest prime factor of 5638, we need to divide it by prime numbers starting from 3 up to √5638 ≈ 75.09. By dividing 5638 by 3, we get 1879 remainder 1. Dividing by 5 gives 1127 remainder 3, while dividing by 7 yields 805 remainder 3. Continuing in this manner, we find that dividing by 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, and 73 does not give a whole number quotient. Finally, dividing 5638 by 79, we get a quotient of 71 without any remainder. Hence, the smallest prime factor of 5638 is 79.
