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 827,523,145
We can find the LCD of numbers 827,523,145 by the prime factorization method or by applying the LCD formula.
The LCD of 827,523,145 is 62715545.
Given numbers has no common factors except 1. So, there LCD is their product i.e 62715545
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 827 and 523. To find the GCF, list down the factors of 827 and 523 and select the highest factor that appears in both lists of factors.
827 : [1, 827]
523 : [1, 523]
From this, we can see that the GCF of 827 and 523 is 1.
Now, put this into the LCD formula.
LCD(827, 523) = ( 827 x 523 ) / 1
LCD(827, 523) = 432521 / 1
LCD(827, 523) = 432521
Step2:
Find the GCF of 432521 and 145. To find the GCF, list down the factors of 432521 and 145 and select the highest factor that appears in both lists of factors.
432521 : [1, 523, 827, 432521]
145 : [1, 5, 29, 145]
From this, we can see that the GCF of 432521 and 145 is 1.
Now, put this into the LCD formula.
LCD(432521, 145) = ( 432521 x 145 ) / 1
LCD(432521, 145) = 62715545 / 1
LCD(432521, 145) = 62715545
LCD of 827,523,145 is 62715545
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 .
