Given numbers are 507,731,858,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,731,858,129 is 8153574.
Find LCM of 507,731,858,129 with Prime Factorization
| 3 | 507, 731, 858, 129 |
| 13 | 169, 731, 286, 43 |
| 43 | 13, 731, 22, 43 |
| 13, 17, 22, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 43 x 13 x 17 x 22 x 1 = 8153574
Therefore, the lowest common multiple of 507,731,858,129 is 8153574.
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.
507 x 731 x 858 x 129 = 41020630794
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.
507 : 1, 3, 13, 39, 169, 507
731 : 1, 17, 43, 731
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,731,858,129, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
731:17x 43
858:2x 3x 11x 13
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 43 = 5031
Therefore, the value for common factors is 5031.
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 = 41020630794/(1x5031)
LCM = 41020630794/5031
LCM = 8153574
Thus, we can understand that the LCM of 507,731,858,129 is 8153574.
