Find the LCD of the terms in the equation.
Tap for more steps…
Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.
y2,2y2,2y2
Since y2,2y2,2y2 contain both numbers and variables, there are two steps to find the LCM. Find LCM for the numeric part 1,2,2 then find LCM for the variable part y2,y2,y2.
The LCM is the smallest positive number that all of the numbers divide into evenly.
1. List the prime factors of each number.
2. Multiply each factor the greatest number of times it occurs in either number.
The number 1 is not a prime number because it only has one positive factor, which is itself.
Not prime
Since 2 has no factors besides 1 and 2.
2 is a prime number
The LCM of 1,2,2 is the result of multiplying all prime factors the greatest number of times they occur in either number.
2
The factors for y2 are y⋅y, which is y multiplied by each other 2 times.
y2=y⋅y
y occurs 2 times.
The LCM of y2,y2,y2 is the result of multiplying all prime factors the greatest number of times they occur in either term.
y⋅y
Multiply y by y.
y2
The LCM for y2,2y2,2y2 is the numeric part 2 multiplied by the variable part.
