Nexus 5 factory reset problem.

I given factory reset on my nexus 5 phone, its almost 45 minutes still it is showing erasing, is it a expected behavior, how much time it will take to reset? can anyone help on this?

This is normal behavior. I've had mine take nearly an hour one time to factory reset.
The LG G2 does this too.
