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 809,655,202
We can find the LCD of numbers 809,655,202 by the prime factorization method or by applying the LCD formula.
The LCD of 809,655,202 is 107038790.
Given numbers has no common factors except 1. So, there LCD is their product i.e 107038790
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 809 and 655. To find the GCF, list down the factors of 809 and 655 and select the highest factor that appears in both lists of factors.
809 : [1, 809]
655 : [1, 5, 131, 655]
From this, we can see that the GCF of 809 and 655 is 1.
Now, put this into the LCD formula.
LCD(809, 655) = ( 809 x 655 ) / 1
LCD(809, 655) = 529895 / 1
LCD(809, 655) = 529895
Step2:
Find the GCF of 529895 and 202. To find the GCF, list down the factors of 529895 and 202 and select the highest factor that appears in both lists of factors.
529895 : [1, 5, 131, 655, 809, 4045, 105979, 529895]
202 : [1, 2, 101, 202]
From this, we can see that the GCF of 529895 and 202 is 1.
Now, put this into the LCD formula.
LCD(529895, 202) = ( 529895 x 202 ) / 1
LCD(529895, 202) = 107038790 / 1
LCD(529895, 202) = 107038790
LCD of 809,655,202 is 107038790
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 .
