The LCM of 539,280,682,868 is 668360.
Find LCM of 539,280,682,868 with Prime Factorization
| 2 | 539, 280, 682, 868 |
| 2 | 539, 140, 341, 434 |
| 7 | 539, 70, 341, 217 |
| 11 | 77, 10, 341, 31 |
| 31 | 7, 10, 31, 31 |
| 7, 10, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 31 x 7 x 10 x 1 x 1 = 668360
Therefore, the lowest common multiple of 539,280,682,868 is 668360.
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.
539 x 280 x 682 x 868 = 89341017920
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.
539 : 1, 7, 11, 49, 77, 539
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
682 : 1, 2, 11, 22, 31, 62, 341, 682
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 539,280,682,868, is 1.
Now, the common factors can be found like this.
539:7x 7x 11
280:2x 2x 2x 5x 7
682:2x 11x 31
868:2x 2x 7x 31
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 11x 31 = 133672
Therefore, the value for common factors is 133672.
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 = 89341017920/(1x133672)
LCM = 89341017920/133672
LCM = 668360
Thus, we can understand that the LCM of 539,280,682,868 is 668360.
