Given numbers are 858,363,921,138,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,363,921,138,489 is 10862600034.
Find LCM of 858,363,921,138,489 with Prime Factorization
| 2 | 858, 363, 921, 138, 489 |
| 3 | 429, 363, 921, 69, 489 |
| 11 | 143, 121, 307, 23, 163 |
| 13, 11, 307, 23, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 11 x 307 x 23 x 163 = 10862600034
Therefore, the lowest common multiple of 858,363,921,138,489 is 10862600034.
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.
858 x 363 x 921 x 138 x 489 = 19357153260588
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
363 : 1, 3, 11, 33, 121, 363
921 : 1, 3, 307, 921
138 : 1, 2, 3, 6, 23, 46, 69, 138
489 : 1, 3, 163, 489
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,363,921,138,489, is 3.
Now, the common factors can be found like this.
858:2x 3x 11x 13
363:3x 11x 11
921:3x 307
138:2x 3x 23
489:3x 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 3x 3x 3x 11 = 594
Therefore, the value for common factors is 594.
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 = 19357153260588/(3x594)
LCM = 19357153260588/1782
LCM = 10862600034
Thus, we can understand that the LCM of 858,363,921,138,489 is 10862600034.
