How do I change the axis exponent of several subplots at once?

Hello,
I was wondering if there is a way to change the exponent value of several subplots (all subplots within a figure) at once.
Currently I'm using:
(source: https://nl.mathworks.com/help/matlab/creating_plots/change-tick-marks-and-tick-labels-of-graph-1.html#d119e2453)
ax = gca;
ax.YAxis.Exponent = 3;
This has to be done to each subplot seperately.
I have tried using:
arrayfun(@(x) YAxis.Exponent(x,3), findobj(gcf,'Type','axes'))
and:
arrayfun(@(x) Exponent(x,3), findobj(gcf,'Type','axes'))
Neither work since Matlab doesn't recognize the functions. Error:
Unrecognized function or variable 'exponent'.
Error in @(x)exponent(x,0)
I think something similar to what I've tried is possible, but I don't know what to put instead of "YAxis.Exponent".
Thank you.

arrayfun(@(axH) set(axH.YAxis, 'Exponent', 3), findobj(gcf,'Type','axes'))
Alternatively:
AxesH = findobj(gcf,'Type','axes');
set([axesH.YAxis], 'Exponent', 6);
Remember that gca and gcf is fragile: As soon as the user clicks on a different figure, unexpected handles are replied. Prefer to store the handles of the axes objects explicitly, e.g.:
AxesH = gobjects(1, 6);
for k = 1:6
AxesH(k) = subplot(2, 3, k);
...
end

Ran in:
subplot(2,1,1); plot(randn(1,20) * 1e5)
subplot(2,1,2); plot(randn(1,20) * 1e5)
yax = get(findobj(gcf,'Type','axes'), 'YAxis');
set([yax{:}], 'Exponent', 3)
