50,000,000

[Math.]  166,666,665,000,000,033,333,333 = 16,666,6663+50,000,0003+33,333,3333.

 

1,000,000,000,000,166,666,665,000,000,033,333,333

= (1012)3+16,666,6663+50,000,0003+33,333,3333. (Generalizable)

 

50,000,000

[Math.]  The sum of all reciprocals of prime numbers S(1/p) is divergent to ¥, but very slowly. Even the sum of the first 50,000,000 terms is still less than 4. The sum 1/2+1/3+…+1/5,195,977 just exceeds 3.

 

50,005,000

[Math.]  (Sequence of numbers 49…950…0 and 50…050…0)

2,499,500,025,000,000 = (24,995,000+25,000,000)2 = 49,995,0002 and 2,500,500,025,000,000 = (25,005,000+25,000,000)2 = 50,005,0002 and 49,995,000+50,005,000 = 100,000,000.

 

50,120,849

[Math.]  2,512,099,504,480,801 = 50,120,8492, ; All  digits are duplicated. (Ref.22)

 

50,232,960

[Math.]  The order of the 8th sporadic group: Janko group J3.

 

50,529,027

[Math.]  A regular polygon with this odd number (product of Fermat prime numbers) of sides is constructible by using only straightedge and compass. 50,529,027 = 3´257´65,537.

 

50,847,534

[Math.]  The number of prime numbers less than 1,000,000,000.

 

50,979,600

[Math.]  Sum of the first 119 cube numbers:

13+23+…+1183+1193 = 49,294,441 = (1+2+…+118+119)2 = 71402.

 

50,997,596

[Math.]  A pair of amicable numbers (50997596, 51737764).

 

 xy,abc,edf

[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.
