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 494,659,796
We can find the LCD of numbers 494,659,796 by the prime factorization method or by applying the LCD formula.
The LCD of 494,659,796 is 129567308.
2 | 494, 659, 796 |
247, 659, 398 |
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 247 x 659 x 398 = 129567308
Thus, we have determined that the LCD of 494,659,796 is 129567308
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 494 and 659. To find the GCF, list down the factors of 494 and 659 and select the highest factor that appears in both lists of factors.
494 : [1, 2, 13, 19, 26, 38, 247, 494]
659 : [1, 659]
From this, we can see that the GCF of 494 and 659 is 1.
Now, put this into the LCD formula.
LCD(494, 659) = ( 494 x 659 ) / 1
LCD(494, 659) = 325546 / 1
LCD(494, 659) = 325546
Step2:
Find the GCF of 325546 and 796. To find the GCF, list down the factors of 325546 and 796 and select the highest factor that appears in both lists of factors.
325546 : [1, 2, 13, 19, 26, 38, 247, 494, 659, 1318, 8567, 12521, 17134, 25042, 162773, 325546]
796 : [1, 2, 4, 199, 398, 796]
From this, we can see that the GCF of 325546 and 796 is 2.
Now, put this into the LCD formula.
LCD(325546, 796) = ( 325546 x 796 ) / 2
LCD(325546, 796) = 259134616 / 2
LCD(325546, 796) = 129567308
LCD of 494,659,796 is 129567308
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 .
