Math question: What is the sum of the digits in the number 6951?

To find the sum of the digits, we add all the digits in the number 6951: 6 + 9 + 5 + 1 = 21. Therefore, the sum of the digits in the number 6951 is 21.

Question: If a number can be divided by both 13 and 17, and when divided by 19 leaves a remainder of 16, what is the largest possible number of times 6951 can be evenly divided by 91?

To find the largest number of times 6951 can be evenly divided by 91, we need to find the common multiples of 13, 17, and 19. Since these are all prime numbers, their least common multiple (LCM) will be the product of the three numbers. Thus, LCM(13, 17, 19) = 13 * 17 * 19 = 4249. Now, to find how many times 6951 can be evenly divided by 91, we need to calculate 4249 (LCM) divided by 91 (GCD of 13 and 17). Therefore, the largest possible number of times 6951 can be evenly divided by 91 is 46.

What is the smallest prime factor of the number formed by the last three digits of 6951 multiplied by 9, minus the sum of its digits, divided by 7 and multiplied by 4, added to the number formed by reversing the digits of 6951?

To find the number formed by the last three digits of 6951 multiplied by 9, we get 869. The sum of its digits is 23, so subtracting that from 869 gives 846. Dividing this by 7 and multiplying by 4 gives 484. If we reverse the digits of 6951, we get 1596. Now, adding the result of the previous calculation, 484, to 1596 gives 2080. The smallest prime factor of 2080 is 2. Therefore, the smallest prime factor of the number described is 2.
