Math question: How many prime factors does the number 1531 have, and what are they?

To determine the prime factors of 1531, we can factorize it by dividing it successively through odd prime numbers. After prime factorization, we find that 1531 has only one prime factor, which is itself (1531 = 17 × 17 × 5 × 2). Therefore, the number 1531 has four prime factors: 17, 17, 5, and 2.

Math question: What is the remainder when 1531 is divided by 8?

When 1531 is divided by 8, the quotient is 191 and the remainder is 3.

Math question: What is the sum of the digits in the number 1531 when multiplied by their position values?

To find the sum of the digits in the number 1531 when multiplied by their position values, we start by multiplying each digit by its position value. The first digit is 1, which is in the thousands place, so we multiply it by 1000. The second digit is 5, which is in the hundreds place, so we multiply it by 100. The third digit is 3, which is in the tens place, so we multiply it by 10. Finally, the fourth digit is 1, which is in the ones place, so we multiply it by 1. Now we add these products together: (1 × 1000) + (5 × 100) + (3 × 10) + (1 × 1) = 1000 + 500 + 30 + 1 = 1531. Hence, the sum of the digits in the number 1531 when multiplied by their position values is 1531.
