Read this article to figure out how to calculate the lowest common denominator of . Learn the two different methods that you can use to find the LCD: the prime factorization method and the LCD formula method. We will explain both these methods in detail so stick around until the very end to understand. Utilise our free LCD Calculator to avail the LCD of numbers easily.
Given numbers are 244,404,196
We can find the LCD of numbers 244,404,196 by the prime factorization method or by applying the LCD formula.
The LCD of 244,404,196 is 1207556.
2 | 244, 404, 196 |
2 | 122, 202, 98 |
61, 101, 49 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
2 x 2 x 61 x 101 x 49 = 1207556
Thus, we have determined that the LCD of 244,404,196 is 1207556
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 244 and 404. To find the GCF, list down the factors of 244 and 404 and select the highest factor that appears in both lists of factors.
244 : [1, 2, 4, 61, 122, 244]
404 : [1, 2, 4, 101, 202, 404]
From this, we can see that the GCF of 244 and 404 is 4.
Now, put this into the LCD formula.
LCD(244, 404) = ( 244 x 404 ) / 4
LCD(244, 404) = 98576 / 4
LCD(244, 404) = 24644
Step2:
Find the GCF of 24644 and 196. To find the GCF, list down the factors of 24644 and 196 and select the highest factor that appears in both lists of factors.
24644 : [1, 2, 4, 61, 101, 122, 202, 244, 404, 6161, 12322, 24644]
196 : [1, 2, 4, 7, 14, 28, 49, 98, 196]
From this, we can see that the GCF of 24644 and 196 is 4.
Now, put this into the LCD formula.
LCD(24644, 196) = ( 24644 x 196 ) / 4
LCD(24644, 196) = 4830224 / 4
LCD(24644, 196) = 1207556
LCD of 244,404,196 is 1207556
Here are some samples of LCD of Numbers calculations.
1. What is the LCD of ?
Answer: LCD of is .
2. How to find LCD of using prime factorization ?
Answer: Just keep dividing by prime numbers until only co-primes are left over. At that point, simply multiply the co-primes with the prime numbers on the left. The answer will be , the LCD.
3. How to Find the LCD of using LCD formula ?
Answer: The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b).
You must first calculate the LCD OF and . Then, find the LCD of that answer and and so on. The answer will be , which is the LCD of .
