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 341,465,300
We can find the LCD of numbers 341,465,300 by the prime factorization method or by applying the LCD formula.
The LCD of 341,465,300 is 102300.
Method to Find Least Common Denominator of 341,465,300 with Prime Factorization
| 3 | 341, 465, 300 |
| 5 | 341, 155, 100 |
| 31 | 341, 31, 20 |
| 11, 1, 20 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
3 x 5 x 31 x 11 x 1 x 20 = 102300
Thus, we have determined that the LCD of 341,465,300 is 102300
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 341 and 465. To find the GCF, list down the factors of 341 and 465 and select the highest factor that appears in both lists of factors.
341 : [1, 11, 31, 341]
465 : [1, 3, 5, 15, 31, 93, 155, 465]
From this, we can see that the GCF of 341 and 465 is 31.
Now, put this into the LCD formula.
LCD(341, 465) = ( 341 x 465 ) / 31
LCD(341, 465) = 158565 / 31
LCD(341, 465) = 5115
Step2:
Find the GCF of 5115 and 300. To find the GCF, list down the factors of 5115 and 300 and select the highest factor that appears in both lists of factors.
5115 : [1, 3, 5, 11, 15, 31, 33, 55, 93, 155, 165, 341, 465, 1023, 1705, 5115]
300 : [1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300]
From this, we can see that the GCF of 5115 and 300 is 15.
Now, put this into the LCD formula.
LCD(5115, 300) = ( 5115 x 300 ) / 15
LCD(5115, 300) = 1534500 / 15
LCD(5115, 300) = 102300
LCD of 341,465,300 is 102300
