Given numbers are 638,609,140,509,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,609,140,509,591 is 13434576540.
Find LCM of 638,609,140,509,591 with Prime Factorization
| 2 | 638, 609, 140, 509, 591 |
| 3 | 319, 609, 70, 509, 591 |
| 7 | 319, 203, 70, 509, 197 |
| 29 | 319, 29, 10, 509, 197 |
| 11, 1, 10, 509, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 11 x 1 x 10 x 509 x 197 = 13434576540
Therefore, the lowest common multiple of 638,609,140,509,591 is 13434576540.
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.
638 x 609 x 140 x 509 x 591 = 16363314225720
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
609 : 1, 3, 7, 21, 29, 87, 203, 609
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
509 : 1, 509
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,609,140,509,591, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
609:3x 7x 29
140:2x 2x 5x 7
509:509
591:3x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 29 = 1218
Therefore, the value for common factors is 1218.
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 = 16363314225720/(1x1218)
LCM = 16363314225720/1218
LCM = 13434576540
Thus, we can understand that the LCM of 638,609,140,509,591 is 13434576540.
