Given numbers are 872,205,106,818,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,205,106,818,990 is 383623071480.
Find LCM of 872,205,106,818,990 with Prime Factorization
| 2 | 872, 205, 106, 818, 990 |
| 5 | 436, 205, 53, 409, 495 |
| 436, 41, 53, 409, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 436 x 41 x 53 x 409 x 99 = 383623071480
Therefore, the lowest common multiple of 872,205,106,818,990 is 383623071480.
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.
872 x 205 x 106 x 818 x 990 = 15344922859200
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
205 : 1, 5, 41, 205
106 : 1, 2, 53, 106
818 : 1, 2, 409, 818
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,205,106,818,990, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
205:5x 41
106:2x 53
818:2x 409
990:2x 3x 3x 5x 11
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 5 = 40
Therefore, the value for common factors is 40.
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 = 15344922859200/(1x40)
LCM = 15344922859200/40
LCM = 383623071480
Thus, we can understand that the LCM of 872,205,106,818,990 is 383623071480.
