Math question: What is the smallest prime number greater than 681?

To find the smallest prime number greater than 681, we start by checking if any number greater than 681 is divisible by 2 or 3, as all prime numbers greater than 3 are of the form 6k ± 1. Starting from 683, we find that 683 is prime because it is not divisible by 2 or 3. Therefore, the smallest prime number greater than 681 is 683.

Math Question: If I multiply 681 by 5 and then subtract 327, what is the result? Math

To find the solution, we multiply 681 by 5, which gives us 3,405. Then we subtract 327 from 3,405, resulting in 3,078. Thus, when 681 is multiplied by 5 and 327 is subtracted, the answer is 3,078.

Math Question: How many multiples of 3 are there between 1 and 681?

To find the number of multiples of 3 between 1 and 681, we can divide the largest number, 681, by 3 and round down to the nearest integer. Dividing 681 by 3 gives us 227, so there are 227 multiples of 3 between 1 and 681.
