Given numbers are 309,382,155,873,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,382,155,873,817 is 4349792959830.
Find LCM of 309,382,155,873,817 with Prime Factorization
| 3 | 309, 382, 155, 873, 817 |
| 103, 382, 155, 291, 817 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 382 x 155 x 291 x 817 = 4349792959830
Therefore, the lowest common multiple of 309,382,155,873,817 is 4349792959830.
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.
309 x 382 x 155 x 873 x 817 = 13049378879490
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.
309 : 1, 3, 103, 309
382 : 1, 2, 191, 382
155 : 1, 5, 31, 155
873 : 1, 3, 9, 97, 291, 873
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,382,155,873,817, is 1.
Now, the common factors can be found like this.
309:3x 103
382:2x 191
155:5x 31
873:3x 3x 97
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 13049378879490/(1x3)
LCM = 13049378879490/3
LCM = 4349792959830
Thus, we can understand that the LCM of 309,382,155,873,817 is 4349792959830.
