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 866,311,261
We can find the LCD of numbers 866,311,261 by the prime factorization method or by applying the LCD formula.
The LCD of 866,311,261 is 70294086.
Given numbers has no common factors except 1. So, there LCD is their product i.e 70294086
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 866 and 311. To find the GCF, list down the factors of 866 and 311 and select the highest factor that appears in both lists of factors.
866 : [1, 2, 433, 866]
311 : [1, 311]
From this, we can see that the GCF of 866 and 311 is 1.
Now, put this into the LCD formula.
LCD(866, 311) = ( 866 x 311 ) / 1
LCD(866, 311) = 269326 / 1
LCD(866, 311) = 269326
Step2:
Find the GCF of 269326 and 261. To find the GCF, list down the factors of 269326 and 261 and select the highest factor that appears in both lists of factors.
269326 : [1, 2, 311, 433, 622, 866, 134663, 269326]
261 : [1, 3, 9, 29, 87, 261]
From this, we can see that the GCF of 269326 and 261 is 1.
Now, put this into the LCD formula.
LCD(269326, 261) = ( 269326 x 261 ) / 1
LCD(269326, 261) = 70294086 / 1
LCD(269326, 261) = 70294086
LCD of 866,311,261 is 70294086
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 .
