Given numbers are 323,787,442,187,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,787,442,187,138 is 5016402534.
Find LCM of 323,787,442,187,138 with Prime Factorization
| 2 | 323, 787, 442, 187, 138 |
| 17 | 323, 787, 221, 187, 69 |
| 19, 787, 13, 11, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 787 x 13 x 11 x 69 = 5016402534
Therefore, the lowest common multiple of 323,787,442,187,138 is 5016402534.
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.
323 x 787 x 442 x 187 x 138 = 2899480664652
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.
323 : 1, 17, 19, 323
787 : 1, 787
442 : 1, 2, 13, 17, 26, 34, 221, 442
187 : 1, 11, 17, 187
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,787,442,187,138, is 1.
Now, the common factors can be found like this.
323:17x 19
787:787
442:2x 13x 17
187:11x 17
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17 = 578
Therefore, the value for common factors is 578.
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 = 2899480664652/(1x578)
LCM = 2899480664652/578
LCM = 5016402534
Thus, we can understand that the LCM of 323,787,442,187,138 is 5016402534.
