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 464,332,197
We can find the LCD of numbers 464,332,197 by the prime factorization method or by applying the LCD formula.
The LCD of 464,332,197 is 7586864.
2 | 464, 332, 197 |
2 | 232, 166, 197 |
116, 83, 197 |
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 2 x 116 x 83 x 197 = 7586864
Thus, we have determined that the LCD of 464,332,197 is 7586864
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 464 and 332. To find the GCF, list down the factors of 464 and 332 and select the highest factor that appears in both lists of factors.
464 : [1, 2, 4, 8, 16, 29, 58, 116, 232, 464]
332 : [1, 2, 4, 83, 166, 332]
From this, we can see that the GCF of 464 and 332 is 4.
Now, put this into the LCD formula.
LCD(464, 332) = ( 464 x 332 ) / 4
LCD(464, 332) = 154048 / 4
LCD(464, 332) = 38512
Step2:
Find the GCF of 38512 and 197. To find the GCF, list down the factors of 38512 and 197 and select the highest factor that appears in both lists of factors.
38512 : [1, 2, 4, 8, 16, 29, 58, 83, 116, 166, 232, 332, 464, 664, 1328, 2407, 4814, 9628, 19256, 38512]
197 : [1, 197]
From this, we can see that the GCF of 38512 and 197 is 1.
Now, put this into the LCD formula.
LCD(38512, 197) = ( 38512 x 197 ) / 1
LCD(38512, 197) = 7586864 / 1
LCD(38512, 197) = 7586864
LCD of 464,332,197 is 7586864
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 .
