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 349,920,303
We can find the LCD of numbers 349,920,303 by the prime factorization method or by applying the LCD formula.
The LCD of 349,920,303 is 97287240.
Given numbers has no common factors except 1. So, there LCD is their product i.e 97287240
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 349 and 920. To find the GCF, list down the factors of 349 and 920 and select the highest factor that appears in both lists of factors.
349 : [1, 349]
920 : [1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920]
From this, we can see that the GCF of 349 and 920 is 1.
Now, put this into the LCD formula.
LCD(349, 920) = ( 349 x 920 ) / 1
LCD(349, 920) = 321080 / 1
LCD(349, 920) = 321080
Step2:
Find the GCF of 321080 and 303. To find the GCF, list down the factors of 321080 and 303 and select the highest factor that appears in both lists of factors.
321080 : [1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 349, 460, 698, 920, 1396, 1745, 2792, 3490, 6980, 8027, 13960, 16054, 32108, 40135, 64216, 80270, 160540, 321080]
303 : [1, 3, 101, 303]
From this, we can see that the GCF of 321080 and 303 is 1.
Now, put this into the LCD formula.
LCD(321080, 303) = ( 321080 x 303 ) / 1
LCD(321080, 303) = 97287240 / 1
LCD(321080, 303) = 97287240
LCD of 349,920,303 is 97287240
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 .
