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 573,736,368
We can find the LCD of numbers 573,736,368 by the prime factorization method or by applying the LCD formula.
The LCD of 573,736,368 is 421728.
2 | 573, 736, 368 |
2 | 573, 368, 184 |
2 | 573, 92, 184 |
2 | 573, 46, 92 |
23 | 573, 23, 46 |
573, 1, 2 |
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 2 x 2 x 23 x 573 x 1 x 2 = 421728
Thus, we have determined that the LCD of 573,736,368 is 421728
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 573 and 736. To find the GCF, list down the factors of 573 and 736 and select the highest factor that appears in both lists of factors.
573 : [1, 3, 191, 573]
736 : [1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736]
From this, we can see that the GCF of 573 and 736 is 1.
Now, put this into the LCD formula.
LCD(573, 736) = ( 573 x 736 ) / 1
LCD(573, 736) = 421728 / 1
LCD(573, 736) = 421728
Step2:
Find the GCF of 421728 and 368. To find the GCF, list down the factors of 421728 and 368 and select the highest factor that appears in both lists of factors.
421728 : [1, 2, 3, 4, 6, 8, 12, 16, 23, 24, 32, 46, 48, 69, 92, 96, 138, 184, 191, 276, 368, 382, 552, 573, 736, 764, 1104, 1146, 1528, 2208, 2292, 3056, 4393, 4584, 6112, 8786, 9168, 13179, 17572, 18336, 26358, 35144, 52716, 70288, 105432, 140576, 210864, 421728]
368 : [1, 2, 4, 8, 16, 23, 46, 92, 184, 368]
From this, we can see that the GCF of 421728 and 368 is 368.
Now, put this into the LCD formula.
LCD(421728, 368) = ( 421728 x 368 ) / 368
LCD(421728, 368) = 155195904 / 368
LCD(421728, 368) = 421728
LCD of 573,736,368 is 421728
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 .
