Math question: What is the largest odd number that can be formed using the digits of 7521?

To find the largest odd number using the digits 7, 5, 2, and 1, we need to place the greatest digit in the leftmost position. Hence, the answer would be 751. The digit 7 is placed in the hundreds position, giving us the largest possible number.

What is the smallest prime number that can be formed by rearranging the digits of 7521?

The smallest prime number that can be formed by rearranging the digits of 7521 is 1257, which is prime because it is not divisible by any prime numbers less than its square root, i.e., 35.47.1257 does not have any factors between 2 and 35.47. Therefore, 1257 is considered prime.

Question: What is the difference between the sum of the digits in the number 7521 and the product of its digits?

To find the sum of the digits in 7521, we add 7 + 5 + 2 + 1, which equals 15. The product of the digits in 7521 is obtained by multiplying 7 × 5 × 2 × 1, resulting in 70. Therefore, the difference between the sum of its digits and the product of its digits is 15 - 70 = -55.
