Answer:
to find the least common denominator list out the multiples of both denominator until you find the smallest multiple that is shared by both
4: 4,8,12,16,20,24,28,32,
7:14,21,28,35,
because 28 is the first shared multiple of 4 and 7,it most be the least common denominator for these two fractions.

Answer:
Below.
Step-by-step explanation:
You can find this by first finding the prime factors of the numbers.
For example, find the LCD of 12 and 16:
12 = 2 * 2 * 3
16 = 2 * 2 * 2 * 2
There are 2 pairs of 2's in the list so only 2 of these four are included in the calculation. All other factors are included.
The LCD is:
2 * 2 * 2 * 2 * 3
= 16*3
= 48.
Find the LCD of 3 and 6
6 = 2 * 3
3 = 3
- so only one of the 3's is included:
LCD = 2*3 = 6.
