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 91,563,977
We can find the LCD of numbers 91,563,977 by the prime factorization method or by applying the LCD formula.
The LCD of 91,563,977 is 50054641.
Given numbers has no common factors except 1. So, there LCD is their product i.e 50054641
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 91 and 563. To find the GCF, list down the factors of 91 and 563 and select the highest factor that appears in both lists of factors.
91 : [1, 7, 13, 91]
563 : [1, 563]
From this, we can see that the GCF of 91 and 563 is 1.
Now, put this into the LCD formula.
LCD(91, 563) = ( 91 x 563 ) / 1
LCD(91, 563) = 51233 / 1
LCD(91, 563) = 51233
Step2:
Find the GCF of 51233 and 977. To find the GCF, list down the factors of 51233 and 977 and select the highest factor that appears in both lists of factors.
51233 : [1, 7, 13, 91, 563, 3941, 7319, 51233]
977 : [1, 977]
From this, we can see that the GCF of 51233 and 977 is 1.
Now, put this into the LCD formula.
LCD(51233, 977) = ( 51233 x 977 ) / 1
LCD(51233, 977) = 50054641 / 1
LCD(51233, 977) = 50054641
LCD of 91,563,977 is 50054641
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 .
