What is the sum of the digits of the number 7886 when each digit is multiplied by its position value (from left to right)?

To find the sum of the digits multiplied by their positions, we can start from the left and multiply each digit by its respective position value: (7x1) + (8x10) + (8x100) + (6x1000). Simplifying this gives us 7 + 80 + 800 + 6000, which equals 6887. Therefore, the sum of the digits of the number 7886 when each digit is multiplied by its position value is 6887.

What is the largest prime factor of the number 7886?

To find the largest prime factor of 7886, we need to factorize it. The prime factorization of 7886 is obtained as follows: 7886 ÷ 2 = 3943 3943 ÷ 17 = 232 232 ÷ 2 = 116 116 ÷ 2 = 58 58 ÷ 2 = 29 So, the largest prime factor of 7886 is 29.

Math Question: How many possible combinations of four different digits can be formed using the number 7886?

To find the number of combinations, we can use the formula for selecting without replacement. As we are selecting four digits from the number 7886, the number of combinations is given by 4!/(4-4)! = 4!/0! = 4x3x2x1/1 = 24. Hence, there are 24 possible combinations of four different digits that can be formed using the number 7886.
