Given numbers are 786,637,640,961,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,637,640,961,382 is 29408218170240.
Find LCM of 786,637,640,961,382 with Prime Factorization
2 | 786, 637, 640, 961, 382 |
393, 637, 320, 961, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 393 x 637 x 320 x 961 x 191 = 29408218170240
Therefore, the lowest common multiple of 786,637,640,961,382 is 29408218170240.
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.
786 x 637 x 640 x 961 x 382 = 117632872680960
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
637 : 1, 7, 13, 49, 91, 637
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
961 : 1, 31, 961
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,637,640,961,382, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
637:7x 7x 13
640:2x 2x 2x 2x 2x 2x 2x 5
961:31x 31
382:2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 117632872680960/(1x4)
LCM = 117632872680960/4
LCM = 29408218170240
Thus, we can understand that the LCM of 786,637,640,961,382 is 29408218170240.
