<PRE><B>Question 803174</B>
Although your question should not have been posted on this section, here we go: 

1. Let the two numbers be x and y
Now, if xy is 8000 and their L.C.M is 800. Therefore, the H.C.F of x and y = 8000/800
=&gt; 10

2. 149 - 5 = 144
101 - 5 = 96
Therefore, find the H.C.F of 144 and 96. The answer is 48.

Hope the solutions helped? </PRE>
