Yes, @Padmaja.
If we want to find max terms of the same function then in the above expression, we just have to write the expression for the false values (0). So we get three expressions that is A'B'C'+A'B'C+A'BC'.

Write the expressions for true values i.e. for 1 values.
First five are true values.
ABC + ABC' + AB'C + AB'C' + A'BC.

How to find the minterm?
A + BC = A (B + B') (C + C') + BC (A + A').
= A (BC + BC '+ B'C + B'C') + BCA + BCA',
= ABC + ABC'+ AB'C + AB'C' + BCA + BCA',
= 2ABC + ABC' + AB'C + AB'C' + A'BC.
A + BC = A (B + B') (C + C') + BC (A + A').
= A (BC + BC '+ B'C + B'C') + BCA + BCA',
= ABC + ABC'+ AB'C + AB'C' + BCA + BCA',
= 2ABC + ABC' + AB'C + AB'C' + A'BC.

Is it like A + BC = (A + B) (A + C).
Then the number of min terms are 2, right?
