Given numbers are 638,411,366,589,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,411,366,589,518 is 2440098705198.
Find LCM of 638,411,366,589,518 with Prime Factorization
| 2 | 638, 411, 366, 589, 518 |
| 3 | 319, 411, 183, 589, 259 |
| 319, 137, 61, 589, 259 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 319 x 137 x 61 x 589 x 259 = 2440098705198
Therefore, the lowest common multiple of 638,411,366,589,518 is 2440098705198.
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.
638 x 411 x 366 x 589 x 518 = 29281184462376
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
411 : 1, 3, 137, 411
366 : 1, 2, 3, 6, 61, 122, 183, 366
589 : 1, 19, 31, 589
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,411,366,589,518, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
411:3x 137
366:2x 3x 61
589:19x 31
518:2x 7x 37
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 3 = 12
Therefore, the value for common factors is 12.
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 = 29281184462376/(1x12)
LCM = 29281184462376/12
LCM = 2440098705198
Thus, we can understand that the LCM of 638,411,366,589,518 is 2440098705198.
