Math Question: What is the sum of the factors of 1421?

To find the factors of 1421, we begin by finding its prime factorization. After some calculations, we find that 1421 is a prime number itself. Hence, it only has two factors: 1 and 1421. Therefore, the sum of the factors of 1421 is 1 + 1421 = 1422.

Math question: What is the smallest prime number greater than 1421 that is divisible by 5?

To find the smallest prime number greater than 1421 divisible by 5, we start by checking if 1426 is prime. Dividing 1426 by 2, 3, 5, or any number up to sqrt(1426), we find no divisors. Therefore, 1426 is a prime number. However, it's not divisible by 5. Let's increment by 1 to 1427. Checking divisibility by 5, we find it isn't divisible either. Incrementing again to 1428, it's clearly divisible by 5, but not prime. Finally, considering 1429, it satisfies both conditions. Thus, the smallest prime number greater than 1421 divisible by 5 is 1429, which is the answer.

Math Question: If the number 1421 is increased by 3 times the difference between its tens and units digit, what is the result?

To find the result, let's break down the number 1421. The tens digit is 2, and the units digit is 1. The difference between these two digits is 1. Multiplying this difference by 3 gives us 3. Adding this to the original number 1421, we get 1424. Therefore, if we increase the number 1421 by 3 times the difference between its tens and units digit, the result is 1424.
