Hi Harshit401,
5, 7 can't be any variable among a, b, c, ... , f, g, since they are prime numbers and they showed up just once.
Hence a, b, c, ... g are from 1, 2, 3, 4, 6, 8, 9
(axbxc)x(dxexf)x(bxgxe) is the type of 2^(3k) * 3^(3n), but axbxcxdxexfxg = 1x2x3x4x6x8x9 = 2^7 * 3^4.
And so b * e = 2^2 * 3^2 and (axbxc) = (dxexf) = (bxgxe) = 2^3 * 3^2.
Therefore g = 2
Happy Studying!
