4,609,866,816

[Math.]   Sum of the first 368 cube numbers:

13+…+3683 = 4,609,866,816 = (1+2+…+368)2 = 67,8962.

4,660,110,225

[Math.]   Sum of the first 369 cube numbers:

13+…+3693 = 4,660,110,225 = (1+2+…+369)2 = 68,2652.

4,666,911,973

[Geology]  The proposed “World Traveling Salesman Problem” for 1,904,711 populated cities and towns on Earth is still unsolved. Its current best lower bound is 7,510,666,782 kilometers (or 4,666,911,973 miles).

4,691,357,802

[Math.]   Three numbers 2,345,678,901, 2,345,678,901×2 = 4,691,357,802 and 2,345,678,901×4 = 9,382,715,604 are all pan-digital numbers. Hence, a pan-digital number factorization: 4,691,357,8022 = 2,345,678,901×9,382,715,604.

x,yzw,abc,def

[Math.]  For any x,yzw = 1000 to 9999, there are always six 6-digit numbers abc,edf such that x,yzw +abc,def is equal to one of 6 digit-rotations of 142,857 and the number x,yzw,abc,def is a multiple of 142,857.

For any x,yzw = 1000 to 9999, there are always twelve 6-digit numbers abc,edf such that x,yzw +abc,def is equal to one of 12 digit-rotations of 076,923 or 153,846 and the number x,yzw,abc,def is a multiple of 76,923.
