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 827,851,893
We can find the LCD of numbers 827,851,893 by the prime factorization method or by applying the LCD formula.
The LCD of 827,851,893 is 628472861.
Given numbers has no common factors except 1. So, there LCD is their product i.e 628472861
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 827 and 851. To find the GCF, list down the factors of 827 and 851 and select the highest factor that appears in both lists of factors.
827 : [1, 827]
851 : [1, 23, 37, 851]
From this, we can see that the GCF of 827 and 851 is 1.
Now, put this into the LCD formula.
LCD(827, 851) = ( 827 x 851 ) / 1
LCD(827, 851) = 703777 / 1
LCD(827, 851) = 703777
Step2:
Find the GCF of 703777 and 893. To find the GCF, list down the factors of 703777 and 893 and select the highest factor that appears in both lists of factors.
703777 : [1, 23, 37, 827, 851, 19021, 30599, 703777]
893 : [1, 19, 47, 893]
From this, we can see that the GCF of 703777 and 893 is 1.
Now, put this into the LCD formula.
LCD(703777, 893) = ( 703777 x 893 ) / 1
LCD(703777, 893) = 628472861 / 1
LCD(703777, 893) = 628472861
LCD of 827,851,893 is 628472861
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 .
