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 452,904,325
We can find the LCD of numbers 452,904,325 by the prime factorization method or by applying the LCD formula.
The LCD of 452,904,325 is 293800.
Method to Find Least Common Denominator of 452,904,325 with Prime Factorization
| 2 | 452, 904, 325 |
| 2 | 226, 452, 325 |
| 113 | 113, 226, 325 |
| 1, 2, 325 |
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 2 x 113 x 1 x 2 x 325 = 293800
Thus, we have determined that the LCD of 452,904,325 is 293800
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 452 and 904. To find the GCF, list down the factors of 452 and 904 and select the highest factor that appears in both lists of factors.
452 : [1, 2, 4, 113, 226, 452]
904 : [1, 2, 4, 8, 113, 226, 452, 904]
From this, we can see that the GCF of 452 and 904 is 452.
Now, put this into the LCD formula.
LCD(452, 904) = ( 452 x 904 ) / 452
LCD(452, 904) = 408608 / 452
LCD(452, 904) = 904
Step2:
Find the GCF of 904 and 325. To find the GCF, list down the factors of 904 and 325 and select the highest factor that appears in both lists of factors.
904 : [1, 2, 4, 8, 113, 226, 452, 904]
325 : [1, 5, 13, 25, 65, 325]
From this, we can see that the GCF of 904 and 325 is 1.
Now, put this into the LCD formula.
LCD(904, 325) = ( 904 x 325 ) / 1
LCD(904, 325) = 293800 / 1
LCD(904, 325) = 293800
LCD of 452,904,325 is 293800
