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 413,637,533
We can find the LCD of numbers 413,637,533 by the prime factorization method or by applying the LCD formula.
The LCD of 413,637,533 is 1540903.
Method to Find Least Common Denominator of 413,637,533 with Prime Factorization
| 7 | 413, 637, 533 |
| 13 | 59, 91, 533 |
| 59, 7, 41 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
7 x 13 x 59 x 7 x 41 = 1540903
Thus, we have determined that the LCD of 413,637,533 is 1540903
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 413 and 637. To find the GCF, list down the factors of 413 and 637 and select the highest factor that appears in both lists of factors.
413 : [1, 7, 59, 413]
637 : [1, 7, 13, 49, 91, 637]
From this, we can see that the GCF of 413 and 637 is 7.
Now, put this into the LCD formula.
LCD(413, 637) = ( 413 x 637 ) / 7
LCD(413, 637) = 263081 / 7
LCD(413, 637) = 37583
Step2:
Find the GCF of 37583 and 533. To find the GCF, list down the factors of 37583 and 533 and select the highest factor that appears in both lists of factors.
37583 : [1, 7, 13, 49, 59, 91, 413, 637, 767, 2891, 5369, 37583]
533 : [1, 13, 41, 533]
From this, we can see that the GCF of 37583 and 533 is 13.
Now, put this into the LCD formula.
LCD(37583, 533) = ( 37583 x 533 ) / 13
LCD(37583, 533) = 20031739 / 13
LCD(37583, 533) = 1540903
LCD of 413,637,533 is 1540903
