The LCM of 580,869,824,638 is 103828120.
Find LCM of 580,869,824,638 with Prime Factorization
| 2 | 580, 869, 824, 638 |
| 2 | 290, 869, 412, 319 |
| 11 | 145, 869, 206, 319 |
| 29 | 145, 79, 206, 29 |
| 5, 79, 206, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 29 x 5 x 79 x 206 x 1 = 103828120
Therefore, the lowest common multiple of 580,869,824,638 is 103828120.
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.
580 x 869 x 824 x 638 = 264969362240
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.
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
869 : 1, 11, 79, 869
824 : 1, 2, 4, 8, 103, 206, 412, 824
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,869,824,638, is 1.
Now, the common factors can be found like this.
580:2x 2x 5x 29
869:11x 79
824:2x 2x 2x 103
638:2x 11x 29
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 11x 29 = 2552
Therefore, the value for common factors is 2552.
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 = 264969362240/(1x2552)
LCM = 264969362240/2552
LCM = 103828120
Thus, we can understand that the LCM of 580,869,824,638 is 103828120.
