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 511,596,789
We can find the LCD of numbers 511,596,789 by the prime factorization method or by applying the LCD formula.
The LCD of 511,596,789 is 240294684.
Given numbers has no common factors except 1. So, there LCD is their product i.e 240294684
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 511 and 596. To find the GCF, list down the factors of 511 and 596 and select the highest factor that appears in both lists of factors.
511 : [1, 7, 73, 511]
596 : [1, 2, 4, 149, 298, 596]
From this, we can see that the GCF of 511 and 596 is 1.
Now, put this into the LCD formula.
LCD(511, 596) = ( 511 x 596 ) / 1
LCD(511, 596) = 304556 / 1
LCD(511, 596) = 304556
Step2:
Find the GCF of 304556 and 789. To find the GCF, list down the factors of 304556 and 789 and select the highest factor that appears in both lists of factors.
304556 : [1, 2, 4, 7, 14, 28, 73, 146, 149, 292, 298, 511, 596, 1022, 1043, 2044, 2086, 4172, 10877, 21754, 43508, 76139, 152278, 304556]
789 : [1, 3, 263, 789]
From this, we can see that the GCF of 304556 and 789 is 1.
Now, put this into the LCD formula.
LCD(304556, 789) = ( 304556 x 789 ) / 1
LCD(304556, 789) = 240294684 / 1
LCD(304556, 789) = 240294684
LCD of 511,596,789 is 240294684
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 .
