Math Question: What is the sum of the prime factors of the number 1511?

To determine the prime factors of 1511, we divide it by prime numbers starting from 2. After division, we find that 1511 = 7 * 7 * 31. Therefore, the prime factors of 1511 are 7 and 31. Consequently, the sum of its prime factors is 7 + 7 + 31 = 45.

Math Question: What is the value of (1511 × 3) ÷ (25 + 6²) + √1511?

To determine the value, we begin by simplifying the expression within the parentheses: (1511 × 3) ÷ (25 + 6²) becomes 4533 ÷ (25 + 36). Next, evaluate the numerator, which is 4533. To simplify the denominator, add 25 and 36, resulting in 61. Now, we can rewrite the expression as 4533 ÷ 61. Performing this division yields approximately 74.31147541. Finally, add the square root of 1511 to this result. The square root of 1511 is roughly 38.86603432. So the final value is approximately 74.31147541 + 38.86603432 = 113.1775097.

Math question: What is the smallest prime number greater than 1511 that is divisible by 7?

The smallest prime number greater than 1511 divisible by 7 is 1513. To find this, we start by checking numbers greater than 1511 one by one. The first number we encounter that is divisible by 7 is 1512 (7 * 216 = 1512). However, 1512 is not a prime number as it is divisible by 2, 3, 7, 8, 12, and other factors. Continuing our search, we find that the next number, 1513, is not divisible by any number other than 1 and itself, making it a prime number. Therefore, 1513 is the smallest prime number greater than 1511 that is divisible by 7.
