What is the prime factorization of the number 1666?

To find the prime factorization of 1666, we divide it by the smallest prime number, which is 2, and get 833 as the result. However, 833 is not divisible by 2. We move on to the next prime number, 3, and find that 833 divided by 3 equals 277 with no remainder. Now, we continue dividing 277 by the next prime numbers, but none of them, such as 5, 7, 11, etc., divide evenly into 277. Therefore, the prime factorization of 1666 is 2 × 833, where 833 is a prime number.

Math question: What is the sum of the squares of the digits in the number 1666?

To find the sum of the squares of the digits in 1666, we break down the number: 1^2 + 6^2 + 6^2 + 6^2 = 1 + 36 + 36 + 36 = 109. Explanation: We start by squaring each digit individually. The digit '1' squared is 1. The digit '6' squared is 36, and since there are three '6's in 1666, we multiply 36 by 3 to get 108. When we sum these squares, we get 1 + 108 = 109. Thus, the sum of the squares of the digits in 1666 is 109.
