Math question: What is the sum of the divisors of 2490?

To find the answer, we can prime factorize 2490 as 2 * 3 * 5 * 83. The sum of the divisors can be calculated using the formula (2^a - 1) * (3^b - 1) * (5^c - 1) * (83^d - 1) / [(2 - 1) * (3 - 1) * (5 - 1) * (83 - 1)]. Since a = 2, b = 1, c = 1, and d = 1, substituting the values gives (2^2 - 1) * (3^1 - 1) * (5^1 - 1) * (83^1 - 1) / [(2 - 1) * (3 - 1) * (5 - 1) * (83 - 1)]. Simplifying, we have (3) * (2) * (4) * (82)/ [1 * 2 * 4 * 82], which results in 6 * 82 = 492. Hence, the sum of the divisors of 2490 is 492.

Math question: If 2490 is divided by 10, multiplied by 3, and then divided by 2, what is the result?

To find the result, we first divide 2490 by 10, which equals 249. Multiplying this by 3 gives us 747. Finally, divide 747 by 2 to get the answer. Therefore, the result is 373.

What is the sum of all odd multiples of 5, less than or equal to 2490?

To find the sum of odd multiples of 5, we first need to find the largest odd multiple of 5 less than or equal to 2490. Dividing 2490 by 5 gives us 498, which is even. So the largest odd multiple is (498-1) * 5 = 2485. Now, let's 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. Plugging in the values, we get Sn = (n/2) * (5 + 2485). The number of terms, n, can be calculated as (l-a)/d + 1, where d is the common difference. In this case, the common difference is 10 (to go from one odd multiple of 5 to the next). So n = (2485-5)/10 + 1 = 248 + 1 = 249. Substituting this back into the sum formula, we have Sn = (249/2) * (5 + 2485) = 124.5 * 2490 = 309,105. Therefore, the sum of all odd multiples of 5, less than or equal to 2490, is 309,105.
