Question

how do i find the LCD of the fraction

Answer 1

Well an easy way is to list all the multiples of each denominator and stop when you find one they have in common.

Answer 2

for example, 1/4 and 1/5. The multiples of 4 are 4, 8, 12, 16, 20, 24...
The multiples of 5 are 5, 10, 15, 20 25...

They have 20 in common.

Multiplying the two together will always give you *a* common denominator, but not necessarily the *least* common denominator.
