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 725,230,373
We can find the LCD of numbers 725,230,373 by the prime factorization method or by applying the LCD formula.
The LCD of 725,230,373 is 12439550.
5 | 725, 230, 373 |
145, 46, 373 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
5 x 145 x 46 x 373 = 12439550
Thus, we have determined that the LCD of 725,230,373 is 12439550
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 725 and 230. To find the GCF, list down the factors of 725 and 230 and select the highest factor that appears in both lists of factors.
725 : [1, 5, 25, 29, 145, 725]
230 : [1, 2, 5, 10, 23, 46, 115, 230]
From this, we can see that the GCF of 725 and 230 is 5.
Now, put this into the LCD formula.
LCD(725, 230) = ( 725 x 230 ) / 5
LCD(725, 230) = 166750 / 5
LCD(725, 230) = 33350
Step2:
Find the GCF of 33350 and 373. To find the GCF, list down the factors of 33350 and 373 and select the highest factor that appears in both lists of factors.
33350 : [1, 2, 5, 10, 23, 25, 29, 46, 50, 58, 115, 145, 230, 290, 575, 667, 725, 1150, 1334, 1450, 3335, 6670, 16675, 33350]
373 : [1, 373]
From this, we can see that the GCF of 33350 and 373 is 1.
Now, put this into the LCD formula.
LCD(33350, 373) = ( 33350 x 373 ) / 1
LCD(33350, 373) = 12439550 / 1
LCD(33350, 373) = 12439550
LCD of 725,230,373 is 12439550
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 .
