Question: How many prime numbers are there between 1 and 1229 (inclusive)?

To find the number of prime numbers between 1 and 1229, we can employ the Sieve of Eratosthenes method. We start by creating a list of numbers from 2 to 1229. Then, we iterate through the list, marking off all the multiples of each number encountered. Next, we count the remaining unmarked numbers. By following this approach, the total number of prime numbers between 1 and 1229 can be computed.

What is the sum of the digits in the number 1229?

The number 1229 has four digits, so we add the individual digits together: 1 + 2 + 2 + 9 = 14. Therefore, the sum of the digits in 1229 is 14.

What is the prime factorization of the number 1229?

To find the prime factorization of 1229, we start by checking if it's divisible by 2, 3, 5, and so on. We observe that dividing 1229 by 2, 3, 5, and 7 doesn't yield whole numbers. However, when we divide it by 11, we get 111, which is divisible by 3: 111 ÷ 3 = 37. Now, we have the prime factorization of 1229 as 11 × 3 × 37. Since 11, 3, and 37 are all prime numbers themselves, this is the prime factorization of 1229.
