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 866,754,239
We can find the LCD of numbers 866,754,239 by the prime factorization method or by applying the LCD formula.
The LCD of 866,754,239 is 78029198.
2 | 866, 754, 239 |
433, 377, 239 |
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 433 x 377 x 239 = 78029198
Thus, we have determined that the LCD of 866,754,239 is 78029198
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 866 and 754. To find the GCF, list down the factors of 866 and 754 and select the highest factor that appears in both lists of factors.
866 : [1, 2, 433, 866]
754 : [1, 2, 13, 26, 29, 58, 377, 754]
From this, we can see that the GCF of 866 and 754 is 2.
Now, put this into the LCD formula.
LCD(866, 754) = ( 866 x 754 ) / 2
LCD(866, 754) = 652964 / 2
LCD(866, 754) = 326482
Step2:
Find the GCF of 326482 and 239. To find the GCF, list down the factors of 326482 and 239 and select the highest factor that appears in both lists of factors.
326482 : [1, 2, 13, 26, 29, 58, 377, 433, 754, 866, 5629, 11258, 12557, 25114, 163241, 326482]
239 : [1, 239]
From this, we can see that the GCF of 326482 and 239 is 1.
Now, put this into the LCD formula.
LCD(326482, 239) = ( 326482 x 239 ) / 1
LCD(326482, 239) = 78029198 / 1
LCD(326482, 239) = 78029198
LCD of 866,754,239 is 78029198
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 .
