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 466,378,622
We can find the LCD of numbers 466,378,622 by the prime factorization method or by applying the LCD formula.
The LCD of 466,378,622 is 27391014.
2 | 466, 378, 622 |
233, 189, 311 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
2 x 233 x 189 x 311 = 27391014
Thus, we have determined that the LCD of 466,378,622 is 27391014
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 466 and 378. To find the GCF, list down the factors of 466 and 378 and select the highest factor that appears in both lists of factors.
466 : [1, 2, 233, 466]
378 : [1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378]
From this, we can see that the GCF of 466 and 378 is 2.
Now, put this into the LCD formula.
LCD(466, 378) = ( 466 x 378 ) / 2
LCD(466, 378) = 176148 / 2
LCD(466, 378) = 88074
Step2:
Find the GCF of 88074 and 622. To find the GCF, list down the factors of 88074 and 622 and select the highest factor that appears in both lists of factors.
88074 : [1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 233, 378, 466, 699, 1398, 1631, 2097, 3262, 4194, 4893, 6291, 9786, 12582, 14679, 29358, 44037, 88074]
622 : [1, 2, 311, 622]
From this, we can see that the GCF of 88074 and 622 is 2.
Now, put this into the LCD formula.
LCD(88074, 622) = ( 88074 x 622 ) / 2
LCD(88074, 622) = 54782028 / 2
LCD(88074, 622) = 27391014
LCD of 466,378,622 is 27391014
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 .
