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 958,536,258
We can find the LCD of numbers 958,536,258 by the prime factorization method or by applying the LCD formula.
The LCD of 958,536,258 is 33119976.
2 | 958, 536, 258 |
479, 268, 129 |
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 479 x 268 x 129 = 33119976
Thus, we have determined that the LCD of 958,536,258 is 33119976
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 958 and 536. To find the GCF, list down the factors of 958 and 536 and select the highest factor that appears in both lists of factors.
958 : [1, 2, 479, 958]
536 : [1, 2, 4, 8, 67, 134, 268, 536]
From this, we can see that the GCF of 958 and 536 is 2.
Now, put this into the LCD formula.
LCD(958, 536) = ( 958 x 536 ) / 2
LCD(958, 536) = 513488 / 2
LCD(958, 536) = 256744
Step2:
Find the GCF of 256744 and 258. To find the GCF, list down the factors of 256744 and 258 and select the highest factor that appears in both lists of factors.
256744 : [1, 2, 4, 8, 67, 134, 268, 479, 536, 958, 1916, 3832, 32093, 64186, 128372, 256744]
258 : [1, 2, 3, 6, 43, 86, 129, 258]
From this, we can see that the GCF of 256744 and 258 is 2.
Now, put this into the LCD formula.
LCD(256744, 258) = ( 256744 x 258 ) / 2
LCD(256744, 258) = 66239952 / 2
LCD(256744, 258) = 33119976
LCD of 958,536,258 is 33119976
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 .
