Given numbers are 379,961,808,468,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,961,808,468,642 is 3684203390088.
Find LCM of 379,961,808,468,642 with Prime Factorization
| 2 | 379, 961, 808, 468, 642 |
| 2 | 379, 961, 404, 234, 321 |
| 3 | 379, 961, 202, 117, 321 |
| 379, 961, 202, 39, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 379 x 961 x 202 x 39 x 107 = 3684203390088
Therefore, the lowest common multiple of 379,961,808,468,642 is 3684203390088.
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.
379 x 961 x 808 x 468 x 642 = 88420881362112
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.
379 : 1, 379
961 : 1, 31, 961
808 : 1, 2, 4, 8, 101, 202, 404, 808
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,961,808,468,642, is 1.
Now, the common factors can be found like this.
379:379
961:31x 31
808:2x 2x 2x 101
468:2x 2x 3x 3x 13
642:2x 3x 107
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 3 = 24
Therefore, the value for common factors is 24.
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 = 88420881362112/(1x24)
LCM = 88420881362112/24
LCM = 3684203390088
Thus, we can understand that the LCM of 379,961,808,468,642 is 3684203390088.
