| Summary:
A series of data samples was collected with the Belle~II detector at the
SuperKEKB collider from March 2019 to June 2022. We determine the integrated
luminosities of these data samples using three distinct methodologies involving
Bhabha ($e^+e^- to e^+e^-(ngamma)$), digamma ($e^+e^- to
gammagamma(ngamma)$), and dimuon ($e^+e^- to mu^+ mu^- (ngamma)$)
events. The total integrated luminosity obtained with Bhabha, digamma, and
dimuon events is ({426.88} $pm$ 0.03 $pm$ {2.61})~fb$^{-1}$, ({429.28} $pm$
0.03 $pm$ {2.62})~fb$^{-1}$, and ({423.99} $pm$ 0.04 $pm$ {3.83})~fb$^{-1}$,
where the first uncertainties are statistical and the second are systematic.
The resulting total integrated luminosity obtained from the combination of the
three methods is ({427.87 $pm$ 2.01})~fb$^{-1}$.
