Question: What is the sum of the even factors of the number 2778?

To find the sum of even factors of the given number 2778, we first need to find all the factors of 2778. The prime factorization of 2778 is 2 × 3 × 463. Now, let's list all possible combinations of these prime factors: 1 × 2778 = 2778 2 × 1389 = 2778 3 × 926 = 2778 6 × 463 = 2778 From these combinations, we can see that the divisors (factors) of 2778 are 1, 2, 3, 6, 463, 926, 1389, and 2778. Out of these factors, the even ones are 2, 6, 926, and 2778. Finally, we add these even factors together: 2 + 6 + 926 + 2778 = 3712. So, the sum of the even factors of 2778 is 3712.

Math Question: If a number is increased by 45% and then decreased by 25%, what is the final value of 2778?

To find the final value, first increase 2778 by 45%: 2778 + (45/100) × 2778 = 2778 + 1250.1 = 4028.1 Next, decrease the result by 25%: 4028.1 - (25/100) × 4028.1 = 4028.1 - 1007.025 = 3018.075 Therefore, the final value of 2778, after increasing by 45% and then decreasing by 25%, is approximately 3018.075.

What is the sum of all the digits in the number 2778?

The number 2778 can be broken down into its digits: 2, 7, 7, and 8. The sum of these digits is 2 + 7 + 7 + 8 = 24.
