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 468,533,361
We can find the LCD of numbers 468,533,361 by the prime factorization method or by applying the LCD formula.
The LCD of 468,533,361 is 6926868.
13 | 468, 533, 361 |
36, 41, 361 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
13 x 36 x 41 x 361 = 6926868
Thus, we have determined that the LCD of 468,533,361 is 6926868
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 468 and 533. To find the GCF, list down the factors of 468 and 533 and select the highest factor that appears in both lists of factors.
468 : [1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468]
533 : [1, 13, 41, 533]
From this, we can see that the GCF of 468 and 533 is 13.
Now, put this into the LCD formula.
LCD(468, 533) = ( 468 x 533 ) / 13
LCD(468, 533) = 249444 / 13
LCD(468, 533) = 19188
Step2:
Find the GCF of 19188 and 361. To find the GCF, list down the factors of 19188 and 361 and select the highest factor that appears in both lists of factors.
19188 : [1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 41, 52, 78, 82, 117, 123, 156, 164, 234, 246, 369, 468, 492, 533, 738, 1066, 1476, 1599, 2132, 3198, 4797, 6396, 9594, 19188]
361 : [1, 19, 361]
From this, we can see that the GCF of 19188 and 361 is 1.
Now, put this into the LCD formula.
LCD(19188, 361) = ( 19188 x 361 ) / 1
LCD(19188, 361) = 6926868 / 1
LCD(19188, 361) = 6926868
LCD of 468,533,361 is 6926868
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.
