Math question: What is the product of the digits in the number 2945?

To find the product of the digits in 2945, we multiply each digit together. So, 2 x 9 x 4 x 5 = 360. The product of the digits in 2945 is 360. Explanation: In the given number 2945, each digit is multiplied to get the product. Starting from the leftmost digit, we multiply 2 by 9 to get 18. Then, multiplying 18 by 4 gives 72. Finally, multiplying 72 by 5 results in 360. Therefore, the product of the digits in the number 2945 is 360.

Math Question: What is the sum of the factors of the number 2945?

To find the sum of the factors of 2945, we need to first determine its prime factorization. After prime factorization, 2945 can be expressed as 5 * 17 * 35. Now, to calculate the sum of factors, we use the formula (a^n - 1)/(a - 1), where 'a' represents the prime factor and 'n' represents the exponent. For 2945, we have (5^2 - 1)/(5 - 1) * (17^1 - 1)/(17 - 1) * (35^1 - 1)/(35 - 1). This simplifies to (24) * (16) * (34), resulting in a sum of 13,824. Hence, the sum of the factors of 2945 is 13,824.

What is the sum of the digits of the number 2945 multiplied by the product of its individual digits divided by the difference between the sum of its first two digits and the sum of its last two digits?

In the given number 2945, the sum of its digits is 2+9+4+5=20. The product of the individual digits is 2*9*4*5=360. The difference between the sum of the first two digits (2+9=11) and the sum of the last two digits (4+5=9) is 11-9=2. Therefore, the required value is (20 * 360) / 2 = 3600.
