Least count means the smallest division that you can measure using that instrument.From zero to 5 A there are 5 divisions .The least count of this ammeter is 1 A,================================-Sorry - I dont understand.You need to explain what least count is and maybe give an example.Try posting a new question with this information included.......
how to calculate least count and why it is multiplied with the readings we get?

Any ammeter will have a range selector.

Suppose the range is selected as 0 to 300 mA.

Count the number of small divisions on the scale.

Suppose there are 30 divisions, then the least count is 300 /30 = 10 m.A

Least count means the smallest division that you can measure using that instrument.
================================

In an instrument a scale reads from zero to 20 A

From zero to 5 A there are 5 divisions .
Hence each division corresponds to 1 A
The least count of this ammeter is 1 A,
================================
