In any scale there is a main scale and some sub divisions.say in between two main scale divisions there is a difference of 1 Voltsand these two divisions are divided into 5 sub divisions then the least count will be the scale denoted by the smallest division.i.e 1/5 = 0.2  V
Least count of ammeter / voltmeter = The highest reading of the instrument / total no. of divisions.
