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 741,502,344
We can find the LCD of numbers 741,502,344 by the prime factorization method or by applying the LCD formula.
The LCD of 741,502,344 is 63980904.
2 | 741, 502, 344 |
741, 251, 172 |
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 741 x 251 x 172 = 63980904
Thus, we have determined that the LCD of 741,502,344 is 63980904
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 741 and 502. To find the GCF, list down the factors of 741 and 502 and select the highest factor that appears in both lists of factors.
741 : [1, 3, 13, 19, 39, 57, 247, 741]
502 : [1, 2, 251, 502]
From this, we can see that the GCF of 741 and 502 is 1.
Now, put this into the LCD formula.
LCD(741, 502) = ( 741 x 502 ) / 1
LCD(741, 502) = 371982 / 1
LCD(741, 502) = 371982
Step2:
Find the GCF of 371982 and 344. To find the GCF, list down the factors of 371982 and 344 and select the highest factor that appears in both lists of factors.
371982 : [1, 2, 3, 6, 13, 19, 26, 38, 39, 57, 78, 114, 247, 251, 494, 502, 741, 753, 1482, 1506, 3263, 4769, 6526, 9538, 9789, 14307, 19578, 28614, 61997, 123994, 185991, 371982]
344 : [1, 2, 4, 8, 43, 86, 172, 344]
From this, we can see that the GCF of 371982 and 344 is 2.
Now, put this into the LCD formula.
LCD(371982, 344) = ( 371982 x 344 ) / 2
LCD(371982, 344) = 127961808 / 2
LCD(371982, 344) = 63980904
LCD of 741,502,344 is 63980904
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 .
