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 227,261,834
We can find the LCD of numbers 227,261,834 by the prime factorization method or by applying the LCD formula.
The LCD of 227,261,834 is 16470666.
3 | 227, 261, 834 |
227, 87, 278 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
3 x 227 x 87 x 278 = 16470666
Thus, we have determined that the LCD of 227,261,834 is 16470666
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 227 and 261. To find the GCF, list down the factors of 227 and 261 and select the highest factor that appears in both lists of factors.
227 : [1, 227]
261 : [1, 3, 9, 29, 87, 261]
From this, we can see that the GCF of 227 and 261 is 1.
Now, put this into the LCD formula.
LCD(227, 261) = ( 227 x 261 ) / 1
LCD(227, 261) = 59247 / 1
LCD(227, 261) = 59247
Step2:
Find the GCF of 59247 and 834. To find the GCF, list down the factors of 59247 and 834 and select the highest factor that appears in both lists of factors.
59247 : [1, 3, 9, 29, 87, 227, 261, 681, 2043, 6583, 19749, 59247]
834 : [1, 2, 3, 6, 139, 278, 417, 834]
From this, we can see that the GCF of 59247 and 834 is 3.
Now, put this into the LCD formula.
LCD(59247, 834) = ( 59247 x 834 ) / 3
LCD(59247, 834) = 49411998 / 3
LCD(59247, 834) = 16470666
LCD of 227,261,834 is 16470666
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 .
