Find LCM of 585,920,738,442,978 with Prime Factorization
| 2 | 585, 920, 738, 442, 978 |
| 3 | 585, 460, 369, 221, 489 |
| 3 | 195, 460, 123, 221, 163 |
| 5 | 65, 460, 41, 221, 163 |
| 13 | 13, 92, 41, 221, 163 |
| 1, 92, 41, 17, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 1 x 92 x 41 x 17 x 163 = 12229088040
Therefore, the lowest common multiple of 585,920,738,442,978 is 12229088040.
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.
585 x 920 x 738 x 442 x 978 = 171696396081600
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
442 : 1, 2, 13, 17, 26, 34, 221, 442
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,920,738,442,978, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
920:2x 2x 2x 5x 23
738:2x 3x 3x 41
442:2x 13x 17
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 3x 5x 13 = 14040
Therefore, the value for common factors is 14040.
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 = 171696396081600/(1x14040)
LCM = 171696396081600/14040
LCM = 12229088040
Thus, we can understand that the LCM of 585,920,738,442,978 is 12229088040.
