Fun Numbers Part 2

37 is another fun number. 37 is a prime number and reversing the number 73 is also a prime number. If you multiply 37 with multiples of 3 see:

37 x 1 x 3 = 111
37 x 2 x 3 = 222
37 x 3 x 3 = 333
37 x 4 x 3 = 444
37 x 5 x 3 = 555 
37 x 6 x 3 = 666
37 x 7 x 3 = 777
37 x 8 x 3 = 888
37 x 9 x 3 = 999

Similarly if you take these numbers 111, 222, 333, 444, 555, 666, 777, 888, 999
Divide these numbers with the sum of the digits ie  1 + 1 + 1=3 , 2+2+2 =6....

gives 37
