Question

If LCM (a,b) = 450, LCM (5,0) = 450, LCM (0,8) = 150, LCM (a,b,c) = 450 and HCF (a,b,c) = 15, then the product of a, b and c is (1) 202500 (2) 1012500 (3) 625000 (4) 187500​

Answer 1

Answer:

1012500

here first suppose the letters a,b,c and the try to assume that the LCM and HCF are one of the factor or multiple of the numbers you have assumed.

Then you will be clear with the a=15,b=450,c=150

then find their products.

And you will finally get the answer which is 1012500
