Given numbers are 684,833,595
We can find the LCD of numbers 684,833,595 by the prime factorization method or by applying the LCD formula.
The LCD of 684,833,595 is 2848860.
Method to Find Least Common Denominator of 684,833,595 with Prime Factorization
| 7 | 684, 833, 595 |
| 17 | 684, 119, 85 |
| 684, 7, 5 |
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 17 x 684 x 7 x 5 = 2848860
Thus, we have determined that the LCD of 684,833,595 is 2848860
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 684 and 833. To find the GCF, list down the factors of 684 and 833 and select the highest factor that appears in both lists of factors.
684 : [1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684]
833 : [1, 7, 17, 49, 119, 833]
From this, we can see that the GCF of 684 and 833 is 1.
Now, put this into the LCD formula.
LCD(684, 833) = ( 684 x 833 ) / 1
LCD(684, 833) = 569772 / 1
LCD(684, 833) = 569772
Step2:
Find the GCF of 569772 and 595. To find the GCF, list down the factors of 569772 and 595 and select the highest factor that appears in both lists of factors.
569772 : [1, 2, 3, 4, 6, 7, 9, 12, 14, 17, 18, 19, 21, 28, 34, 36, 38, 42, 49, 51, 57, 63, 68, 76, 84, 98, 102, 114, 119, 126, 133, 147, 153, 171, 196, 204, 228, 238, 252, 266, 294, 306, 323, 342, 357, 399, 441, 476, 532, 588, 612, 646, 684, 714, 798, 833, 882, 931, 969, 1071, 1197, 1292, 1428, 1596, 1666, 1764, 1862, 1938, 2142, 2261, 2394, 2499, 2793, 2907, 3332, 3724, 3876, 4284, 4522, 4788, 4998, 5586, 5814, 6783, 7497, 8379, 9044, 9996, 11172, 11628, 13566, 14994, 15827, 16758, 20349, 27132, 29988, 31654, 33516, 40698, 47481, 63308, 81396, 94962, 142443, 189924, 284886, 569772]
595 : [1, 5, 7, 17, 35, 85, 119, 595]
From this, we can see that the GCF of 569772 and 595 is 119.
Now, put this into the LCD formula.
LCD(569772, 595) = ( 569772 x 595 ) / 119
LCD(569772, 595) = 339014340 / 119
LCD(569772, 595) = 2848860
LCD of 684,833,595 is 2848860
