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 952,302,714
We can find the LCD of numbers 952,302,714 by the prime factorization method or by applying the LCD formula.
The LCD of 952,302,714 is 431256.
Method to Find Least Common Denominator of 952,302,714 with Prime Factorization
| 2 | 952, 302, 714 |
| 7 | 476, 151, 357 |
| 17 | 68, 151, 51 |
| 4, 151, 3 |
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 7 x 17 x 4 x 151 x 3 = 431256
Thus, we have determined that the LCD of 952,302,714 is 431256
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 952 and 302. To find the GCF, list down the factors of 952 and 302 and select the highest factor that appears in both lists of factors.
952 : [1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952]
302 : [1, 2, 151, 302]
From this, we can see that the GCF of 952 and 302 is 2.
Now, put this into the LCD formula.
LCD(952, 302) = ( 952 x 302 ) / 2
LCD(952, 302) = 287504 / 2
LCD(952, 302) = 143752
Step2:
Find the GCF of 143752 and 714. To find the GCF, list down the factors of 143752 and 714 and select the highest factor that appears in both lists of factors.
143752 : [1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 151, 238, 302, 476, 604, 952, 1057, 1208, 2114, 2567, 4228, 5134, 8456, 10268, 17969, 20536, 35938, 71876, 143752]
714 : [1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714]
From this, we can see that the GCF of 143752 and 714 is 238.
Now, put this into the LCD formula.
LCD(143752, 714) = ( 143752 x 714 ) / 238
LCD(143752, 714) = 102638928 / 238
LCD(143752, 714) = 431256
LCD of 952,302,714 is 431256
