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 233,200,391
We can find the LCD of numbers 233,200,391 by the prime factorization method or by applying the LCD formula.
The LCD of 233,200,391 is 18220600.
Given numbers has no common factors except 1. So, there LCD is their product i.e 18220600
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 233 and 200. To find the GCF, list down the factors of 233 and 200 and select the highest factor that appears in both lists of factors.
233 : [1, 233]
200 : [1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200]
From this, we can see that the GCF of 233 and 200 is 1.
Now, put this into the LCD formula.
LCD(233, 200) = ( 233 x 200 ) / 1
LCD(233, 200) = 46600 / 1
LCD(233, 200) = 46600
Step2:
Find the GCF of 46600 and 391. To find the GCF, list down the factors of 46600 and 391 and select the highest factor that appears in both lists of factors.
46600 : [1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200, 233, 466, 932, 1165, 1864, 2330, 4660, 5825, 9320, 11650, 23300, 46600]
391 : [1, 17, 23, 391]
From this, we can see that the GCF of 46600 and 391 is 1.
Now, put this into the LCD formula.
LCD(46600, 391) = ( 46600 x 391 ) / 1
LCD(46600, 391) = 18220600 / 1
LCD(46600, 391) = 18220600
LCD of 233,200,391 is 18220600
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 .
