Given numbers are 580,349,940,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 580,349,940,455 is 865750340.
Find LCM of 580,349,940,455 with Prime Factorization
| 2 | 580, 349, 940, 455 |
| 2 | 290, 349, 470, 455 |
| 5 | 145, 349, 235, 455 |
| 29, 349, 47, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 349 x 47 x 91 = 865750340
Therefore, the lowest common multiple of 580,349,940,455 is 865750340.
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 349 x 940 x 455 = 86575034000
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
349 : 1, 349
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
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 580,349,940,455, is 1.
Now, the common factors can be found like this.
580:2x 2x 5x 29
349:349
940:2x 2x 5x 47
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 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 86575034000/(1x100)
LCM = 86575034000/100
LCM = 865750340
Thus, we can understand that the LCM of 580,349,940,455 is 865750340.
