Sum of the first 1107 square numbers

We define square numbers as numbers that when squared will equal a whole number. Thus, the list of the first square numbers starts with 1, 4, 9, 16, and so on.

What is the sum of the first 1107 square numbers, you ask? Here we will give you the formula to calculate the first 1107 square numbers and then we will show you how to calculate the first 1107 square numbers using the formula.

The formula to calculate the first n square numbers is displayed below:

		n(n + 1) × (2(n) + 1)
		6

To calculate the sum of the first 1107 square numbers, we enter n = 1107 into our formula to get this:

		1107(1107 + 1) × (2(1107) + 1)
		6

First, calculate each section of the numerator: 1107(1107 + 1) equals 1226556 and (2(1107) + 1) equals 2215. Therefore, the problem above becomes this:

		1226556 × 2215
		6

Next, we calculate 1226556 times 2215 which equals 2716821540. Now our problem looks like this:

		2716821540
		6

Finally, divide the numerator by the denominator to get our answer:

2716821540 ÷ 6 = 452803590

There you go. The sum of the first 1107 square numbers is 452803590.
