Math question: What is the least prime number greater than 4947 that can be expressed as the sum of two distinct prime numbers?

The least prime number greater than 4947 is 4967. To find this, we must check prime numbers greater than 4947, and the sum of two distinct prime numbers. While there are many prime numbers greater than 4947, we need to find the one that can be expressed as the sum of two distinct prime numbers. After checking, we find that 4967 can be expressed as the sum of the distinct primes 2, and 4965 (4967 = 2 + 4965). Thus, 4967 is the least prime number greater than 4947 that can be expressed as the sum of two distinct prime numbers.

Question: What is the product of the prime factors of the number 4947?

To find the prime factors of 4947, we divide it by prime numbers starting from 2. 4947 divided by 2 is not an integer, so we move on. Dividing 4947 by 3 gives us 1649, which is also not divisible by 3. Continuing, we try dividing by 5, and we get 989. Now, 989 is divisible by 23 (43 times), so we divide again and are left with the prime factor 43. Combining all the prime factors 3, 23, and 43, the product of these primes is 3 x 23 x 43 = 2898, which is the final answer.

What is the sum of the digits of the square root of 4947, when rounded to the nearest whole number?

To find the square root of 4947, we get approximately 70.37. Rounding it to the nearest whole number, we have 70. Now, calculating the sum of its digits, 7 + 0 equals 7. Therefore, the answer is 7.
