Math question: What is the sum of all the digits in the number 2940?

To find the sum of the digits in 2940, we consider each digit separately. The thousands place has a digit of 2, the hundreds place has a digit of 9, the tens place has a digit of 4, and the units place has a digit of 0. Adding these digits together: 2 + 9 + 4 + 0 = 15. Thus, the sum of all the digits in the number 2940 is 15.

Math Question: What is the sum of the first 10 positive multiples of 294?

To find the sum, we can use the formula for the sum of an arithmetic series: S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. For this question, the first term (a) is 294, and we want to find the sum of the first 10 multiples of 294. The last term (l) can be calculated by multiplying the number of terms by the common difference, which in this case is also 294, giving us l = 10 * 294 = 2940. Substituting these values into the formula, we have S = (10/2)(294 + 2940) = 5 * 3234 = 16170. Therefore, the sum of the first 10 positive multiples of 294 is 16170.

Math question: Find the largest prime factor of the number 2940.

To find the largest prime factor of 2940, we need to analyze the prime factors of this number. First, we check if 2 is a factor, which is true. 2940 divided by 2 gives us 1470. Next, we check 3, and it is also a factor. Dividing 1470 by 3 yields 490. Continuing, we observe that 5 is another prime factor. Dividing 490 by 5 gives us 98. Moving on, we see that 7 is also a factor. Dividing 98 by 7 gives us 14, and at this point, we should stop to avoid reaching a non-prime factor. Thus, the largest prime factor of 2940 is 7.
