Given numbers are 668,589,810,703,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,589,810,703,455 is 536524918020.
Find LCM of 668,589,810,703,455 with Prime Factorization
| 2 | 668, 589, 810, 703, 455 |
| 5 | 334, 589, 405, 703, 455 |
| 19 | 334, 589, 81, 703, 91 |
| 334, 31, 81, 37, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 334 x 31 x 81 x 37 x 91 = 536524918020
Therefore, the lowest common multiple of 668,589,810,703,455 is 536524918020.
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.
668 x 589 x 810 x 703 x 455 = 101939734423800
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.
668 : 1, 2, 4, 167, 334, 668
589 : 1, 19, 31, 589
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
703 : 1, 19, 37, 703
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,589,810,703,455, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
589:19x 31
810:2x 3x 3x 3x 3x 5
703:19x 37
455:5x 7x 13
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 19 = 190
Therefore, the value for common factors is 190.
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 = 101939734423800/(1x190)
LCM = 101939734423800/190
LCM = 536524918020
Thus, we can understand that the LCM of 668,589,810,703,455 is 536524918020.
