How to Find LCD of 837,938,496 ?

Given numbers are 837,938,496

We can find the LCD of numbers 837,938,496 by the prime factorization method or by applying the LCD formula.

The LCD of 837,938,496 is 6280848.

Method to Find Least Common Denominator of 837,938,496 with Prime Factorization

2	837, 938, 496
31	837, 469, 248
	27, 469, 8

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 31 x 27 x 469 x 8 = 6280848

Thus, we have determined that the LCD of 837,938,496 is 6280848

LCD Formula to Find LCD of 837,938,496

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

Step1:

Find the GCF of 837 and 938. To find the GCF, list down the factors of 837 and 938 and select the highest factor that appears in both lists of factors.

837 : [1, 3, 9, 27, 31, 93, 279, 837]

938 : [1, 2, 7, 14, 67, 134, 469, 938]

From this, we can see that the GCF of 837 and 938 is 1.

Now, put this into the LCD formula.

LCD(837, 938) = ( 837 x 938 ) / 1

LCD(837, 938) = 785106 / 1

LCD(837, 938) = 785106

Step2:

Find the GCF of 785106 and 496. To find the GCF, list down the factors of 785106 and 496 and select the highest factor that appears in both lists of factors.

785106 : [1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 31, 42, 54, 62, 63, 67, 93, 126, 134, 186, 189, 201, 217, 279, 378, 402, 434, 469, 558, 603, 651, 837, 938, 1206, 1302, 1407, 1674, 1809, 1953, 2077, 2814, 3618, 3906, 4154, 4221, 5859, 6231, 8442, 11718, 12462, 12663, 14539, 18693, 25326, 29078, 37386, 43617, 56079, 87234, 112158, 130851, 261702, 392553, 785106]

496 : [1, 2, 4, 8, 16, 31, 62, 124, 248, 496]

From this, we can see that the GCF of 785106 and 496 is 62.

Now, put this into the LCD formula.

LCD(785106, 496) = ( 785106 x 496 ) / 62

LCD(785106, 496) = 389412576 / 62

LCD(785106, 496) = 6280848

LCD of 837,938,496 is 6280848
