Given numbers are 389,638,935,914,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,638,935,914,385 is 67484408530.
Find LCM of 389,638,935,914,385 with Prime Factorization
| 2 | 389, 638, 935, 914, 385 |
| 5 | 389, 319, 935, 457, 385 |
| 11 | 389, 319, 187, 457, 77 |
| 389, 29, 17, 457, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 389 x 29 x 17 x 457 x 7 = 67484408530
Therefore, the lowest common multiple of 389,638,935,914,385 is 67484408530.
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.
389 x 638 x 935 x 914 x 385 = 81656134321300
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.
389 : 1, 389
638 : 1, 2, 11, 22, 29, 58, 319, 638
935 : 1, 5, 11, 17, 55, 85, 187, 935
914 : 1, 2, 457, 914
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,638,935,914,385, is 1.
Now, the common factors can be found like this.
389:389
638:2x 11x 29
935:5x 11x 17
914:2x 457
385:5x 7x 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 5x 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 81656134321300/(1x1210)
LCM = 81656134321300/1210
LCM = 67484408530
Thus, we can understand that the LCM of 389,638,935,914,385 is 67484408530.
