 LCD = 10
 LCD = 12
 LCD = 3
 LCD = 45
 LCD = 42
stays the same  LCD = 8
 LCD = 2
stays the same  LCD = 7
Solution for finding LCD:
To find the LCD, we need to find the common factors of the denominators and the highest power of each factor that is required to make all the denominators equal.
For example, to find the LCD of, we don’t need to do anything since the denominator is already a prime number.
 The factors of 3 are 3 and 1
 The factors of 4 are 2 and 2
 The highest power of 2 required is 2 and the highest power of 3 required is 1
So, the LCD for the rest of the numbers are: 
 12

 3

 45

 42

 2 (stays the same)
