Math question: What is the sum of the digits of the number 8749?

The number 8749 is a four-digit number. The sum of its digits can be found by adding each digit together. 8 + 7 + 4 + 9 = 28 Therefore, the sum of the digits in the number 8749 is 28.

Math question for the number 8749: How many four-digit numbers can be formed using all the digits of 8749 without repetition? (Assuming zero at the beginning is not allowed.)

To find the number of four-digit numbers, we first notice that there are 4 choices for the first digit, 3 choices for the second, 2 choices for the third, and finally, 1 choice for the fourth digit. Thus, the number of four-digit numbers is equal to 4 × 3 × 2 × 1 = 24. Therefore, there are 24 different four-digit numbers that can be formed using all the digits of 8749 without repetition.

Math Question: What is the largest prime factor of the number 8749? Math

To find the largest prime factor of 8749, we begin by checking divisibility by prime numbers. Starting with dividing by 2, we see that 8749 is not divisible by 2.
