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 853,343,112
We can find the LCD of numbers 853,343,112 by the prime factorization method or by applying the LCD formula.
The LCD of 853,343,112 is 4681264.
7 | 853, 343, 112 |
853, 49, 16 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
7 x 853 x 49 x 16 = 4681264
Thus, we have determined that the LCD of 853,343,112 is 4681264
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 853 and 343. To find the GCF, list down the factors of 853 and 343 and select the highest factor that appears in both lists of factors.
853 : [1, 853]
343 : [1, 7, 49, 343]
From this, we can see that the GCF of 853 and 343 is 1.
Now, put this into the LCD formula.
LCD(853, 343) = ( 853 x 343 ) / 1
LCD(853, 343) = 292579 / 1
LCD(853, 343) = 292579
Step2:
Find the GCF of 292579 and 112. To find the GCF, list down the factors of 292579 and 112 and select the highest factor that appears in both lists of factors.
292579 : [1, 7, 49, 343, 853, 5971, 41797, 292579]
112 : [1, 2, 4, 7, 8, 14, 16, 28, 56, 112]
From this, we can see that the GCF of 292579 and 112 is 7.
Now, put this into the LCD formula.
LCD(292579, 112) = ( 292579 x 112 ) / 7
LCD(292579, 112) = 32768848 / 7
LCD(292579, 112) = 4681264
LCD of 853,343,112 is 4681264
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 .
