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 781,373,819
We can find the LCD of numbers 781,373,819 by the prime factorization method or by applying the LCD formula.
The LCD of 781,373,819 is 238585347.
Given numbers has no common factors except 1. So, there LCD is their product i.e 238585347
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 781 and 373. To find the GCF, list down the factors of 781 and 373 and select the highest factor that appears in both lists of factors.
781 : [1, 11, 71, 781]
373 : [1, 373]
From this, we can see that the GCF of 781 and 373 is 1.
Now, put this into the LCD formula.
LCD(781, 373) = ( 781 x 373 ) / 1
LCD(781, 373) = 291313 / 1
LCD(781, 373) = 291313
Step2:
Find the GCF of 291313 and 819. To find the GCF, list down the factors of 291313 and 819 and select the highest factor that appears in both lists of factors.
291313 : [1, 11, 71, 373, 781, 4103, 26483, 291313]
819 : [1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819]
From this, we can see that the GCF of 291313 and 819 is 1.
Now, put this into the LCD formula.
LCD(291313, 819) = ( 291313 x 819 ) / 1
LCD(291313, 819) = 238585347 / 1
LCD(291313, 819) = 238585347
LCD of 781,373,819 is 238585347
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 .
