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 967,916,290
We can find the LCD of numbers 967,916,290 by the prime factorization method or by applying the LCD formula.
The LCD of 967,916,290 is 128436940.
2 | 967, 916, 290 |
967, 458, 145 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
2 x 967 x 458 x 145 = 128436940
Thus, we have determined that the LCD of 967,916,290 is 128436940
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 967 and 916. To find the GCF, list down the factors of 967 and 916 and select the highest factor that appears in both lists of factors.
967 : [1, 967]
916 : [1, 2, 4, 229, 458, 916]
From this, we can see that the GCF of 967 and 916 is 1.
Now, put this into the LCD formula.
LCD(967, 916) = ( 967 x 916 ) / 1
LCD(967, 916) = 885772 / 1
LCD(967, 916) = 885772
Step2:
Find the GCF of 885772 and 290. To find the GCF, list down the factors of 885772 and 290 and select the highest factor that appears in both lists of factors.
885772 : [1, 2, 4, 229, 458, 916, 967, 1934, 3868, 221443, 442886, 885772]
290 : [1, 2, 5, 10, 29, 58, 145, 290]
From this, we can see that the GCF of 885772 and 290 is 2.
Now, put this into the LCD formula.
LCD(885772, 290) = ( 885772 x 290 ) / 2
LCD(885772, 290) = 256873880 / 2
LCD(885772, 290) = 128436940
LCD of 967,916,290 is 128436940
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 .
