We know that x, y, Z and a are natural numbers, And x < y < Z, and 1 / x + 1 / y + 1 / z = a, find the value of X, y, Z, a

We know that x, y, Z and a are natural numbers, And x < y < Z, and 1 / x + 1 / y + 1 / z = a, find the value of X, y, Z, a

Let x, y, Z be natural numbers, x < y < Z
We know that x > = 1, Y > = 2, z > = 3
So 0=
