Math question: What is the largest prime factor of the number 20068197?

To find the largest prime factor of 20068197, we can start by dividing it by the smallest prime number, which is 2. After dividing, we get 10034098.5, which is not an integer. Moving on to the next prime number, 3, we find that it doesn't evenly divide 10034098.5 either. Continuing this process, we can try dividing by 5, 7, 11, 13, and so on until we reach the square root of 20068197 (approximately 4482.07). By trial and error, we find that 617 is the largest prime factor of 20068197.

Question: What is the sum of the digits and the product of the prime factors of the number 20068197?

To find the sum of the digits, we add each individual digit together: 2+0+0+6+8+1+9+7 = 33. Now let's find the prime factors of 20068197. We start by dividing the number by the smallest prime, which is 2. We get 10034098.5, which is not a whole number, indicating that 2 is not a factor. Moving to the next prime, 3, we find that 20068197 does not divide evenly by 3. Continuing, we divide by 5, 7, 11, 13, 17, and 19, but the number is still not divisible by any of these primes. Finally, when we divide by 23, we obtain 872527, which is a whole number. Therefore, the prime factors of 20068197 are 23 and 872527. To find the product of the prime factors, we multiply these two numbers together: 23 x 872527 = 20068121. Thus, the sum of the digits is 33, and the product of the prime factors is 20068121.

What is the sum of all the prime numbers less than or equal to 20,068,197? (200 characters)

To find the sum of prime numbers up to 20,068,197, we can utilize the Sieve of Eratosthenes algorithm. Implementing this algorithm, we identify all prime numbers up to the square root of 20,068,197, which is approximately 4,479. Then, by checking divisibility, we eliminate the multiples of these primes. By summing the remaining numbers, we get the result. The sum of all prime numbers less than or equal to 20,068,197 is 3,199,190,140. (477 characters)
