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 947,244,369
We can find the LCD of numbers 947,244,369 by the prime factorization method or by applying the LCD formula.
The LCD of 947,244,369 is 85264092.
Given numbers has no common factors except 1. So, there LCD is their product i.e 85264092
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 947 and 244. To find the GCF, list down the factors of 947 and 244 and select the highest factor that appears in both lists of factors.
947 : [1, 947]
244 : [1, 2, 4, 61, 122, 244]
From this, we can see that the GCF of 947 and 244 is 1.
Now, put this into the LCD formula.
LCD(947, 244) = ( 947 x 244 ) / 1
LCD(947, 244) = 231068 / 1
LCD(947, 244) = 231068
Step2:
Find the GCF of 231068 and 369. To find the GCF, list down the factors of 231068 and 369 and select the highest factor that appears in both lists of factors.
231068 : [1, 2, 4, 61, 122, 244, 947, 1894, 3788, 57767, 115534, 231068]
369 : [1, 3, 9, 41, 123, 369]
From this, we can see that the GCF of 231068 and 369 is 1.
Now, put this into the LCD formula.
LCD(231068, 369) = ( 231068 x 369 ) / 1
LCD(231068, 369) = 85264092 / 1
LCD(231068, 369) = 85264092
LCD of 947,244,369 is 85264092
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 .
