Given numbers are 519,645,985,657,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 519,645,985,657,768 is 1232412583680.
Find LCM of 519,645,985,657,768 with Prime Factorization
| 3 | 519, 645, 985, 657, 768 |
| 5 | 173, 215, 985, 219, 256 |
| 173, 43, 197, 219, 256 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 173 x 43 x 197 x 219 x 256 = 1232412583680
Therefore, the lowest common multiple of 519,645,985,657,768 is 1232412583680.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
519 x 645 x 985 x 657 x 768 = 166375698796800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
519 : 1, 3, 173, 519
645 : 1, 3, 5, 15, 43, 129, 215, 645
985 : 1, 5, 197, 985
657 : 1, 3, 9, 73, 219, 657
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 519,645,985,657,768, is 1.
Now, the common factors can be found like this.
519:3x 173
645:3x 5x 43
985:5x 197
657:3x 3x 73
768:2x 2x 2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 166375698796800/(1x135)
LCM = 166375698796800/135
LCM = 1232412583680
Thus, we can understand that the LCM of 519,645,985,657,768 is 1232412583680.
