x for the first number and y for the second number so,
$xy=147$
and
$x=\frac{147}{y}$
substituting in the second statement, we get:
$\frac{147}{y}+3y=$ a minimum value
if we assume some function:
${f}^{\prime }\left(y\right)=3-\frac{147}{{y}^{2}}$
y=0,7
$x=\frac{147}{7}=21$
the two numbers are 7 and 21
