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 615,722,877
We can find the LCD of numbers 615,722,877 by the prime factorization method or by applying the LCD formula.
The LCD of 615,722,877 is 389414310.
Given numbers has no common factors except 1. So, there LCD is their product i.e 389414310
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 615 and 722. To find the GCF, list down the factors of 615 and 722 and select the highest factor that appears in both lists of factors.
615 : [1, 3, 5, 15, 41, 123, 205, 615]
722 : [1, 2, 19, 38, 361, 722]
From this, we can see that the GCF of 615 and 722 is 1.
Now, put this into the LCD formula.
LCD(615, 722) = ( 615 x 722 ) / 1
LCD(615, 722) = 444030 / 1
LCD(615, 722) = 444030
Step2:
Find the GCF of 444030 and 877. To find the GCF, list down the factors of 444030 and 877 and select the highest factor that appears in both lists of factors.
444030 : [1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 41, 57, 82, 95, 114, 123, 190, 205, 246, 285, 361, 410, 570, 615, 722, 779, 1083, 1230, 1558, 1805, 2166, 2337, 3610, 3895, 4674, 5415, 7790, 10830, 11685, 14801, 23370, 29602, 44403, 74005, 88806, 148010, 222015, 444030]
877 : [1, 877]
From this, we can see that the GCF of 444030 and 877 is 1.
Now, put this into the LCD formula.
LCD(444030, 877) = ( 444030 x 877 ) / 1
LCD(444030, 877) = 389414310 / 1
LCD(444030, 877) = 389414310
LCD of 615,722,877 is 389414310
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 .
