Given numbers are 539,936,205
We can find the LCD of numbers 539,936,205 by the prime factorization method or by applying the LCD formula.
The LCD of 539,936,205 is 103423320.
Given numbers has no common factors except 1. So, there LCD is their product i.e 103423320
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 539 and 936. To find the GCF, list down the factors of 539 and 936 and select the highest factor that appears in both lists of factors.
539 : [1, 7, 11, 49, 77, 539]
936 : [1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936]
From this, we can see that the GCF of 539 and 936 is 1.
Now, put this into the LCD formula.
LCD(539, 936) = ( 539 x 936 ) / 1
LCD(539, 936) = 504504 / 1
LCD(539, 936) = 504504
Step2:
Find the GCF of 504504 and 205. To find the GCF, list down the factors of 504504 and 205 and select the highest factor that appears in both lists of factors.
504504 : [1, 2, 3, 4, 6, 7, 8, 9, 11, 12, 13, 14, 18, 21, 22, 24, 26, 28, 33, 36, 39, 42, 44, 49, 52, 56, 63, 66, 72, 77, 78, 84, 88, 91, 98, 99, 104, 117, 126, 132, 143, 147, 154, 156, 168, 182, 196, 198, 231, 234, 252, 264, 273, 286, 294, 308, 312, 364, 392, 396, 429, 441, 462, 468, 504, 539, 546, 572, 588, 616, 637, 693, 728, 792, 819, 858, 882, 924, 936, 1001, 1078, 1092, 1144, 1176, 1274, 1287, 1386, 1617, 1638, 1716, 1764, 1848, 1911, 2002, 2156, 2184, 2548, 2574, 2772, 3003, 3234, 3276, 3432, 3528, 3822, 4004, 4312, 4851, 5096, 5148, 5544, 5733, 6006, 6468, 6552, 7007, 7644, 8008, 9009, 9702, 10296, 11466, 12012, 12936, 14014, 15288, 18018, 19404, 21021, 22932, 24024, 28028, 36036, 38808, 42042, 45864, 56056, 63063, 72072, 84084, 126126, 168168, 252252, 504504]
205 : [1, 5, 41, 205]
From this, we can see that the GCF of 504504 and 205 is 1.
Now, put this into the LCD formula.
LCD(504504, 205) = ( 504504 x 205 ) / 1
LCD(504504, 205) = 103423320 / 1
LCD(504504, 205) = 103423320
LCD of 539,936,205 is 103423320
