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 268,353,105
We can find the LCD of numbers 268,353,105 by the prime factorization method or by applying the LCD formula.
The LCD of 268,353,105 is 9933420.
Given numbers has no common factors except 1. So, there LCD is their product i.e 9933420
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 268 and 353. To find the GCF, list down the factors of 268 and 353 and select the highest factor that appears in both lists of factors.
268 : [1, 2, 4, 67, 134, 268]
353 : [1, 353]
From this, we can see that the GCF of 268 and 353 is 1.
Now, put this into the LCD formula.
LCD(268, 353) = ( 268 x 353 ) / 1
LCD(268, 353) = 94604 / 1
LCD(268, 353) = 94604
Step2:
Find the GCF of 94604 and 105. To find the GCF, list down the factors of 94604 and 105 and select the highest factor that appears in both lists of factors.
94604 : [1, 2, 4, 67, 134, 268, 353, 706, 1412, 23651, 47302, 94604]
105 : [1, 3, 5, 7, 15, 21, 35, 105]
From this, we can see that the GCF of 94604 and 105 is 1.
Now, put this into the LCD formula.
LCD(94604, 105) = ( 94604 x 105 ) / 1
LCD(94604, 105) = 9933420 / 1
LCD(94604, 105) = 9933420
LCD of 268,353,105 is 9933420
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 .
