Question: What is the sum of the first 100 multiples of 39, starting from 39?

To find the sum, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. Given that the first term (a) is 39 and the common difference is 39, we can calculate the last term using the formula (l = a + (n - 1)d). As the number of terms (n) is 100, we have l = 39 + (100 - 1) * 39 = 3900. Plugging these values into the sum formula, we get Sn = (100/2)(39 + 3900) = 50 * 3939 = 196,950. Thus, the sum of the first 100 multiples of 39 is 196,950.

What is the largest prime factor of 3900?

To determine the largest prime factor of 3900, we need to prime factorize it. The prime factorization of 3900 is 2^2 * 3 * 5^2 * 13. Among these prime factors, the largest one is 13. Hence, the largest prime factor of 3900 is 13.

Math Question: What is the maximum number of unique two-digit prime factors that divide evenly into 3900?

To find the factors of 3900, we start by factoring it: 3900 = 2^2 * 3^1 * 5^2 * 13^1. The number of two-digit prime factors can be determined by using the exponents. In this case, there are three different two-digit prime factors: 2, 5, and 13. Thus, the maximum number of unique two-digit prime factors that divide evenly into 3900 is 3.
