Given numbers are 580,129,731,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 580,129,731,856 is 272195160.
Find LCM of 580,129,731,856 with Prime Factorization
| 2 | 580, 129, 731, 856 |
| 2 | 290, 129, 731, 428 |
| 43 | 145, 129, 731, 214 |
| 145, 3, 17, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 145 x 3 x 17 x 214 = 272195160
Therefore, the lowest common multiple of 580,129,731,856 is 272195160.
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 129 x 731 x 856 = 46817567520
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
129 : 1, 3, 43, 129
731 : 1, 17, 43, 731
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,129,731,856, is 1.
Now, the common factors can be found like this.
580:2x 2x 5x 29
129:3x 43
731:17x 43
856:2x 2x 2x 107
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 43 = 172
Therefore, the value for common factors is 172.
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 = 46817567520/(1x172)
LCM = 46817567520/172
LCM = 272195160
Thus, we can understand that the LCM of 580,129,731,856 is 272195160.
