The LCM of 116,539,396,391,686 is 1540153692.
Find LCM of 116,539,396,391,686 with Prime Factorization
| 2 | 116, 539, 396, 391, 686 |
| 2 | 58, 539, 198, 391, 343 |
| 7 | 29, 539, 99, 391, 343 |
| 7 | 29, 77, 99, 391, 49 |
| 11 | 29, 11, 99, 391, 7 |
| 29, 1, 9, 391, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 11 x 29 x 1 x 9 x 391 x 7 = 1540153692
Therefore, the lowest common multiple of 116,539,396,391,686 is 1540153692.
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.
116 x 539 x 396 x 391 x 686 = 6641142719904
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.
116 : 1, 2, 4, 29, 58, 116
539 : 1, 7, 11, 49, 77, 539
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
391 : 1, 17, 23, 391
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 116,539,396,391,686, is 1.
Now, the common factors can be found like this.
116:2x 2x 29
539:7x 7x 11
396:2x 2x 3x 3x 11
391:17x 23
686:2x 7x 7x 7
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 7x 7x 11 = 4312
Therefore, the value for common factors is 4312.
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 = 6641142719904/(1x4312)
LCM = 6641142719904/4312
LCM = 1540153692
Thus, we can understand that the LCM of 116,539,396,391,686 is 1540153692.
