Given numbers are 387,979,979,702,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,979,979,702,408 is 2009542392.
Find LCM of 387,979,979,702,408 with Prime Factorization
| 2 | 387, 979, 979, 702, 408 |
| 3 | 387, 979, 979, 351, 204 |
| 3 | 129, 979, 979, 117, 68 |
| 11 | 43, 979, 979, 39, 68 |
| 89 | 43, 89, 89, 39, 68 |
| 43, 1, 1, 39, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 89 x 43 x 1 x 1 x 39 x 68 = 2009542392
Therefore, the lowest common multiple of 387,979,979,702,408 is 2009542392.
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.
387 x 979 x 979 x 702 x 408 = 106236468095472
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.
387 : 1, 3, 9, 43, 129, 387
979 : 1, 11, 89, 979
979 : 1, 11, 89, 979
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,979,979,702,408, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
979:11x 89
979:11x 89
702:2x 3x 3x 3x 13
408:2x 2x 2x 3x 17
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 11x 89 = 52866
Therefore, the value for common factors is 52866.
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 = 106236468095472/(1x52866)
LCM = 106236468095472/52866
LCM = 2009542392
Thus, we can understand that the LCM of 387,979,979,702,408 is 2009542392.
