Math question: If 6491 is multiplied by 12 and then divided by 3, what is the result when 100 is added to it?

To solve the equation, first multiply 6491 by 12 which gives 77892. Then, divide 77892 by 3 to get 25964. Finally, add 100 to the result, which is 26064. Therefore, the sum is 26064.

Question: Find the largest prime factor of the number 6491.

To find the largest prime factor of 6491, we start by checking divisibility with prime numbers. Testing for divisibility, we realize that 2 does not divide 6491. Proceeding further, even numbers can be ruled out as 6491 is odd. Next, dividing 6491 by 3 leaves a remainder of 4, so it is not divisible by 3 either. Continuing with 5, 6491 is not divisible as its last digit is not 0 or 5. Moving to 7, dividing 6491 by 7 gives a remainder of 5. Proceeding to 11, 6491 is not divisible as subtracting the sum of its digits in odd positions from the sum of digits in even positions gives 3, which is not divisible by 11. Similarly, attempting division by other prime numbers yields no satisfying result. Finally, trying division by 97 works perfectly, yielding a quotient of 67 and no remainder. Therefore, the largest prime factor of 6491 is 97.

Question: What is the remainder when the number 6491 is divided by 10?

When 6491 is divided by 10, the remainder is 1. This is because the remainder of a number divided by 10 is always equal to the last digit of that number. In this case, the last digit of 6491 is 1. Thus, 6491 divided by 10 leaves a remainder of 1.
