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 943,916,828
We can find the LCD of numbers 943,916,828 by the prime factorization method or by applying the LCD formula.
The LCD of 943,916,828 is 7774092.
2 | 943, 916, 828 |
2 | 943, 458, 414 |
23 | 943, 229, 207 |
41, 229, 9 |
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 23 x 41 x 229 x 9 = 7774092
Thus, we have determined that the LCD of 943,916,828 is 7774092
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 943 and 916. To find the GCF, list down the factors of 943 and 916 and select the highest factor that appears in both lists of factors.
943 : [1, 23, 41, 943]
916 : [1, 2, 4, 229, 458, 916]
From this, we can see that the GCF of 943 and 916 is 1.
Now, put this into the LCD formula.
LCD(943, 916) = ( 943 x 916 ) / 1
LCD(943, 916) = 863788 / 1
LCD(943, 916) = 863788
Step2:
Find the GCF of 863788 and 828. To find the GCF, list down the factors of 863788 and 828 and select the highest factor that appears in both lists of factors.
863788 : [1, 2, 4, 23, 41, 46, 82, 92, 164, 229, 458, 916, 943, 1886, 3772, 5267, 9389, 10534, 18778, 21068, 37556, 215947, 431894, 863788]
828 : [1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828]
From this, we can see that the GCF of 863788 and 828 is 92.
Now, put this into the LCD formula.
LCD(863788, 828) = ( 863788 x 828 ) / 92
LCD(863788, 828) = 715216464 / 92
LCD(863788, 828) = 7774092
LCD of 943,916,828 is 7774092
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 .
