I did check the above answerers answers, and they are wrong :P
a,b,c,d,e,f = 1,2,5,5,4,6.
You could go and solve this by the usual elimination methods, but for something this large its far better to use a calculator or online solver. Google for 'simultaneous equation solver' and you'll find heaps.
(Just to confirm above answers are wrong: for those numbers you get 4a + b + 5d + 2e + 3f = 69, not 57.)

I did my own checking using matrices and row reductions and got the same answers as Stephen:
A = 1
B = 2
C = 5
D = 5
E = 4
F = 6

abcde x f = gggggg Descartando numeros para: a, f y g: 0. / f : a million El numero gggggg se puede escribir gx11111 Sacando mcm a 11111= 3x7x11x13x37 Osea : abcde x f = gx3x7x11x13x37 f podría ser: g , 3 ó 7. Pero f y g son diferentes. Ojo que f tiene a million dígito. f = 3 ó 7. Con f=3 : g podría ser a million o 2. (No puede ser mayor a 2 porque sino abcde serian 6 digitos ) Con g=a million abcde=37037... descartado Con g=2 abcde=74074... descartado Con f=7 : g podría ser a million,2,3,4,5 ó 6. (Mayor a 6 daría un abcde de 6 digitos.) Con g=a million abcde=15873.. descartado x el #7 Con g=2 abcde=31746... ídem Con g=3 abcde=47619... ídem Con g=4 abcde=63492 ... descartado x el #4 Con g=5 abcde=79365... descartado x el #7 Con g=6 abcde= 95238 ... esta es l. a. respuesta 95238 x 7 = 666666.

You have six equations and six unknowns, which should be sufficient to solve for a -> f. The approach to this problem is to solve for each letter variable in terms of the other 5 variables from one equation and substitute the result in another equation until you have reduced the problem to one equation of all "A"s, for example. Then solve for A.
Good luck! Hope this helps!

c=4.47826
d=4.47826
e=4.34782
f=7.3913
these answers are 100% correct check them if you want.
dont believe that steven check them they are right. i just did that and they were giving me the right answer
