m and n

Two natural numbers m and n have natural divisors

$a_{1} , a_{2} , ................ , a_{p}$

and

$b_{1} , b_{2} , ........................ b_{q}$

and it is known that

$a_{1} + a_{2} + .............................+ a_{p} = b_{1} + b_{2} + ......................... + b_{q}$

$\frac{1}{a_{1}} + .................... \frac{1}{a_{p}} = \frac{1}{b_{1}} + ............................. + \frac{1}{b_{q}}$

Find the value of $\frac{m}{n}$
