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 839,898,563
We can find the LCD of numbers 839,898,563 by the prime factorization method or by applying the LCD formula.
The LCD of 839,898,563 is 424176586.
Given numbers has no common factors except 1. So, there LCD is their product i.e 424176586
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 839 and 898. To find the GCF, list down the factors of 839 and 898 and select the highest factor that appears in both lists of factors.
839 : [1, 839]
898 : [1, 2, 449, 898]
From this, we can see that the GCF of 839 and 898 is 1.
Now, put this into the LCD formula.
LCD(839, 898) = ( 839 x 898 ) / 1
LCD(839, 898) = 753422 / 1
LCD(839, 898) = 753422
Step2:
Find the GCF of 753422 and 563. To find the GCF, list down the factors of 753422 and 563 and select the highest factor that appears in both lists of factors.
753422 : [1, 2, 449, 839, 898, 1678, 376711, 753422]
563 : [1, 563]
From this, we can see that the GCF of 753422 and 563 is 1.
Now, put this into the LCD formula.
LCD(753422, 563) = ( 753422 x 563 ) / 1
LCD(753422, 563) = 424176586 / 1
LCD(753422, 563) = 424176586
LCD of 839,898,563 is 424176586
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 .
