HEY MATE UR ANSWER IS HERE.....

HOPE IT HELPS.....

Answer 2

prime factorisation of 8= 2×2×2=2^3

9=3^2

25=5^2

lcm= 1800 in lcm we know that we have to choose the greatest power of the common factors therefore we are multiplying the three numbers.

hcf=1 in prime factorisation of three numbers we are not finding any common factor therefore hcf is 1.

hope it helps.
