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 583,121,684
We can find the LCD of numbers 583,121,684 by the prime factorization method or by applying the LCD formula.
The LCD of 583,121,684 is 4386492.
11 | 583, 121, 684 |
53, 11, 684 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
11 x 53 x 11 x 684 = 4386492
Thus, we have determined that the LCD of 583,121,684 is 4386492
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 583 and 121. To find the GCF, list down the factors of 583 and 121 and select the highest factor that appears in both lists of factors.
583 : [1, 11, 53, 583]
121 : [1, 11, 121]
From this, we can see that the GCF of 583 and 121 is 11.
Now, put this into the LCD formula.
LCD(583, 121) = ( 583 x 121 ) / 11
LCD(583, 121) = 70543 / 11
LCD(583, 121) = 6413
Step2:
Find the GCF of 6413 and 684. To find the GCF, list down the factors of 6413 and 684 and select the highest factor that appears in both lists of factors.
6413 : [1, 11, 53, 121, 583, 6413]
684 : [1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684]
From this, we can see that the GCF of 6413 and 684 is 1.
Now, put this into the LCD formula.
LCD(6413, 684) = ( 6413 x 684 ) / 1
LCD(6413, 684) = 4386492 / 1
LCD(6413, 684) = 4386492
LCD of 583,121,684 is 4386492
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 .
