[EECS]  470K(W) is one of standard numerical values for resistors (of tolerance class 5%).

472,036

[Math.]  A base system of multigrade equalities:

1+6+7+17+18+23 = 72 = 2+3+11+13+21+22

12+62+72+172+182+232 = 1,228 = 22+32+112+132+212+222

13+63+73+173+183+233 = 23,472 = 23+33+113+133+213+223

14+64+74+174+184+234 = 472,036 = 24+34+114+134+214+224

15+65+75+175+185+235 = 9,770,352= 25+35+115+135+215+225. (References [??])

Multigrade equatilities still hold by adding any integer n to every base term in both sides.  Hence, the base equality always has number 1 appearing in one side.

474,474

[Math.]  A sequence of palindromic numbers: 77, 77×78 = 6,006 and 77×78×79 = 474,474.

474,552

[Math.]  474,552 = (–474+552)3 = 783.

476,190

[Math.]  Multiples of 047619 (the period of the rational number 1/21 = 0.047619047619… or 0.047619) by 4, 10, 13, 16 and 19 yield 5 other digit-rotations of the number itself: 190476, 476190, 619047, 761904 and 904761, respectively.
