=2,048/32
=64
-OR-
DETAILED METHOD
STEP 1:
Find prime factors of denominators.
8/64
64: 2 x 2 x 2 x 2 x 2 x 2
8/32
32: 2 x 2 x 2 x 2 x 2
STEP 2:
If factors occur more than once, multiply them the greater number of times they occur.
2 x 2 x 2 x 2 x 2 x 2= 64
ANSWER: The LCM of 8/64 and 8/32 is 64.
Hope this helps! :)
