42,713,568

[Math.]  85,427,136 = 2×42,713,568 = 4×21,356,784 = 6×14,237,856, all 3 factorizations using 3 permutations of the number itself (digit 9 is not used).

 

42,968,025

[Math.]  Sum of the first 114 cube numbers:

13+23+…+1133+1143 = 42,968,025 = (1+2+…+113+114)2 = 65552 

 

xy,abc,def

[Math.]  For any xy = 10 to 99, there are always six 6-digit numbers abc,edf such that the sum (xy+abc,def) is equal to one of 6 digit-rotations of 142,857 and the number xy,abc,def is a multiple of 142,857.

 

For any xy = 10 to 99, there are always twelve 6-digit numbers abc,edf such that the sum (xy+abc,def) is equal to one of 12 digit-rotations of 076,923 or 153,846 and the number xy,abc,def is a multiple of 76,923.
