Given numbers are 682,784,379,806,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,784,379,806,164 is 54005359408.
Find LCM of 682,784,379,806,164 with Prime Factorization
| 2 | 682, 784, 379, 806, 164 |
| 2 | 341, 392, 379, 403, 82 |
| 31 | 341, 196, 379, 403, 41 |
| 11, 196, 379, 13, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 11 x 196 x 379 x 13 x 41 = 54005359408
Therefore, the lowest common multiple of 682,784,379,806,164 is 54005359408.
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.
682 x 784 x 379 x 806 x 164 = 26786658266368
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
379 : 1, 379
806 : 1, 2, 13, 26, 31, 62, 403, 806
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,784,379,806,164, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
784:2x 2x 2x 2x 7x 7
379:379
806:2x 13x 31
164:2x 2x 41
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 2x 31 = 496
Therefore, the value for common factors is 496.
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 = 26786658266368/(1x496)
LCM = 26786658266368/496
LCM = 54005359408
Thus, we can understand that the LCM of 682,784,379,806,164 is 54005359408.
