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 997,554,533
We can find the LCD of numbers 997,554,533 by the prime factorization method or by applying the LCD formula.
The LCD of 997,554,533 is 294396154.
Given numbers has no common factors except 1. So, there LCD is their product i.e 294396154
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 997 and 554. To find the GCF, list down the factors of 997 and 554 and select the highest factor that appears in both lists of factors.
997 : [1, 997]
554 : [1, 2, 277, 554]
From this, we can see that the GCF of 997 and 554 is 1.
Now, put this into the LCD formula.
LCD(997, 554) = ( 997 x 554 ) / 1
LCD(997, 554) = 552338 / 1
LCD(997, 554) = 552338
Step2:
Find the GCF of 552338 and 533. To find the GCF, list down the factors of 552338 and 533 and select the highest factor that appears in both lists of factors.
552338 : [1, 2, 277, 554, 997, 1994, 276169, 552338]
533 : [1, 13, 41, 533]
From this, we can see that the GCF of 552338 and 533 is 1.
Now, put this into the LCD formula.
LCD(552338, 533) = ( 552338 x 533 ) / 1
LCD(552338, 533) = 294396154 / 1
LCD(552338, 533) = 294396154
LCD of 997,554,533 is 294396154
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 .
