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 313,665,547
We can find the LCD of numbers 313,665,547 by the prime factorization method or by applying the LCD formula.
The LCD of 313,665,547 is 113855315.
Given numbers has no common factors except 1. So, there LCD is their product i.e 113855315
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 313 and 665. To find the GCF, list down the factors of 313 and 665 and select the highest factor that appears in both lists of factors.
313 : [1, 313]
665 : [1, 5, 7, 19, 35, 95, 133, 665]
From this, we can see that the GCF of 313 and 665 is 1.
Now, put this into the LCD formula.
LCD(313, 665) = ( 313 x 665 ) / 1
LCD(313, 665) = 208145 / 1
LCD(313, 665) = 208145
Step2:
Find the GCF of 208145 and 547. To find the GCF, list down the factors of 208145 and 547 and select the highest factor that appears in both lists of factors.
208145 : [1, 5, 7, 19, 35, 95, 133, 313, 665, 1565, 2191, 5947, 10955, 29735, 41629, 208145]
547 : [1, 547]
From this, we can see that the GCF of 208145 and 547 is 1.
Now, put this into the LCD formula.
LCD(208145, 547) = ( 208145 x 547 ) / 1
LCD(208145, 547) = 113855315 / 1
LCD(208145, 547) = 113855315
LCD of 313,665,547 is 113855315
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 .
