How to Find LCD of 465,871,384 ?

Given numbers are 465,871,384

We can find the LCD of numbers 465,871,384 by the prime factorization method or by applying the LCD formula.

The LCD of 465,871,384 is 51841920.


Method to Find Least Common Denominator of 465,871,384 with Prime Factorization

3 465, 871, 384
155, 871, 128

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 155 x 871 x 128 = 51841920

Thus, we have determined that the LCD of 465,871,384 is 51841920

LCD Formula to Find LCD of 465,871,384

The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)


Step1:

Find the GCF of 465 and 871. To find the GCF, list down the factors of 465 and 871 and select the highest factor that appears in both lists of factors.

465 : [1, 3, 5, 15, 31, 93, 155, 465]

871 : [1, 13, 67, 871]

From this, we can see that the GCF of 465 and 871 is 1.

Now, put this into the LCD formula.

LCD(465, 871) = ( 465 x 871 ) / 1

LCD(465, 871) = 405015 / 1

LCD(465, 871) = 405015


Step2:

Find the GCF of 405015 and 384. To find the GCF, list down the factors of 405015 and 384 and select the highest factor that appears in both lists of factors.

405015 : [1, 3, 5, 13, 15, 31, 39, 65, 67, 93, 155, 195, 201, 335, 403, 465, 871, 1005, 1209, 2015, 2077, 2613, 4355, 6045, 6231, 10385, 13065, 27001, 31155, 81003, 135005, 405015]

384 : [1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384]

From this, we can see that the GCF of 405015 and 384 is 3.

Now, put this into the LCD formula.

LCD(405015, 384) = ( 405015 x 384 ) / 3

LCD(405015, 384) = 155525760 / 3

LCD(405015, 384) = 51841920

LCD of 465,871,384 is 51841920
