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 353,751,672
We can find the LCD of numbers 353,751,672 by the prime factorization method or by applying the LCD formula.
The LCD of 353,751,672 is 178149216.
Given numbers has no common factors except 1. So, there LCD is their product i.e 178149216
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 353 and 751. To find the GCF, list down the factors of 353 and 751 and select the highest factor that appears in both lists of factors.
353 : [1, 353]
751 : [1, 751]
From this, we can see that the GCF of 353 and 751 is 1.
Now, put this into the LCD formula.
LCD(353, 751) = ( 353 x 751 ) / 1
LCD(353, 751) = 265103 / 1
LCD(353, 751) = 265103
Step2:
Find the GCF of 265103 and 672. To find the GCF, list down the factors of 265103 and 672 and select the highest factor that appears in both lists of factors.
265103 : [1, 353, 751, 265103]
672 : [1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672]
From this, we can see that the GCF of 265103 and 672 is 1.
Now, put this into the LCD formula.
LCD(265103, 672) = ( 265103 x 672 ) / 1
LCD(265103, 672) = 178149216 / 1
LCD(265103, 672) = 178149216
LCD of 353,751,672 is 178149216
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 .
